IntroductionThe use of natural fibers such as sisal andkenaf as reinforcement or filler in com-posites continues to receive much atten-tion from numerous researchers acrossthe world. This is due to the broad rangeof advantages offered by these fibers par-ticularly low density, low volumetric cost,high specific properties and more impor-tantly biodegradability. The use of naturalfibers, however, may lead to unsatisfacto-ry mechanical properties of the compos-ites due to among others limited compat-ibility between the polar fiber and thenon-polar polymer matrix. Natural fibersare polar materials due to the presence ofhydroxyls groups in the fiber cell walls.Various methods have been employed tooptimize fiber–matrix compatibility (oradhesion) by modification of fiber surfaceproperties via chemical treatments suchas alkalization [1-5]. Alkalization or alkali treatment is one ofthe most used chemical treatments ofnatural fibers when used to reinforcethermoplastics and thermosets [1]. Thistreatment leads to removal of non-struc-tural materials such as wax and oils fromthe fiber surface [1], partial removal ofthe fiber cell wall polymers, i.e. hemicel-luloses and lignin [2, 3] and depolymer-ization of cellulose chains [1]. In this study alkali treatment was per-formed on kenaf bast fiber. The effect oftreatment times on the morphology andstructure of the fiber were determined viascanning electron microscopy (SEM), x-ray diffraction (XRD), fourier transforminfrared (FTIR) spectroscopy and atomicforce microscopy (AFM).

ExperimentalKenaf bast fiber with an average fiberlength of 7.70 cm was purchased fromLembaga Kenaf dan Tembakau Negara(LKTN) Malaysia. The Fiber was sub-merged in 6% solution of sodium hydrox-ide for 1, 2, 3, 4 and 5 hours of immer-sion at room temperature, rinsed withdeionized water and then neutralized indilute solution of glacial acetic acid.Finally the fiber was rinsed again withdeionized water and dried at room tem-perature for 24 h. The treated fiber wasobserved in FESEM model Supra 35 VP to

characterize the fiber surface morphology.Crystallinity index, Crl, of the fiber wasdetermined using an X-Ray Diffractometertype D8 Bruker. The equatorial diffractionpatterns (2θ) were recorded from 10 to35o using Cu-Kα radiation at 40 kV and 40mA. The crystallinity index, Crl, was calcu-lated using the following equation [5].

where I002 is the counter reading at peakintensity at a 2θ angle close to 22o repre-senting crystalline region and Iam is thecounter reading at a 2θ angle of around18o representing amorphous region innatural fibers. The infrared spectra of thefiber before and after treatment weremeasured in the spectral range of 4000 to500 cm-1 using a Perkin Elmer FTIR spec-trometer. A total of 32 scans were takenfor each sample with a resolution of 1 cm-1. The samples were prepared usinga KBr disk method. AFM characterizationswere carried out in contact mode, using aNanoNavi SPA 300HM. Surface roughnessof the fibers was analyzed based onimages obtained over a 2 μm x 2 µm area.

Results and discussionScanning electron microscopy

Observations of the treated fiber surface(Figure. 1(B)) reveal that the alkali treat-ment has resulted in the removal ofcementing materials from the interfibrillarregion and impurities from the fiber sur-face. The very similar observations havebeen reported by other researchers forgrass fibers [3]. Removal of the cement-ing materials, i.e. hemicelluloses andlignin revealed that the kenaf bast fiberconsists of aligned microfibrils. Theexposed interfibrillar region increased thespecific surface area of the fiber to comein contact with the polymer matrix duringcomposite fabrication[4]. Removal ofimpurities resulted in cleaner andsmoother fiber surface of the treatedfiber.

X-ray diffraction Crystallinity index of kenaf bast fiberimproved after 1, 2, 3 and 4 hours ofalkali treatment (Figure2). The maximumimprovement was observed after 1 hour

of treatment (+ 11%). Beyond that thecrystallinity index of the treated fiberreduced but the values were higher thanthat of the untreated fiber. After 5 hoursof treatment the crystallinity index of thetreated fiber was found to be slightlylower than the control. Changes in crys-tallinity through alkali treatment for natu-ral fibers have been reported by manyresearchers [2,5]. The improved crys-tallinity of natural fiber after the treat-ment has been attributed to the removalof the cementing materials, hemicellulos-es and lignin, which probably leads to abetter packing of cellulose chains [2] andthickening of the fiber cell wall [5]. Inaddition of removal of the cementingmaterials, alkali treatment also depoly-merizes cellulose chains [1]. After 5 hoursof treatment, excess depolymerization ofcellulose chains damage the fiber cell wallleading to an overall decrease in the cys-tallinity index of the treated fiber [5].

Fourier transform infrared (FTIR) spec-troscopyExamination of Figure 3 revealed severalchanges on the FTIR spectra of the kenafbast fibers after the alkali treatment. Thetransmission peak at 1737 cm-1, assignedto a C=O stretching vibration of carboxylicacid or ester, was found to disappear fol-lowing the alkali treatment due to the

removal of hemicelluloses [3]. Otherchanges that have been reported resultedfrom the alkali treatment are reduction inthe intensity of the transmission peaks at1515 and 1254 cm-1 which are assignedto the benzene ring vibration of lignin anda C-O stretching stretching vibration of

the acetyl group in lignin component,respectively [3]. Reductions in thesetransmission peaks indicate removal oflignin from the fiber after the alkali treat-ment [3].

Atomic force microscopy (AFM)AFM images of untreated and alkali treat-ed kenaf bast fiber are shown in Fig. 4.These images illustrats the reduction ofsurface roughness via alkali treatment ofthe fiber. The untreated fiber exhibited aroot mean square (RMS) roughness valueof 21.6 nm, whereas the alkali treatedfiber exhibited 11.21 nm of RMS rough-ness. This suggests that removal of somelow-molecular weight materials as well asimpurities from the fiber surface resultingin a decrease in the fiber surface rough-ness following the alkali treatment.

ConclusionsThe morphology and structure of kenafbast fiber changed after the alkali treat-ment. SEM micrographs reveal that thefiber surface became cleaner andsmoother after the alkali treatment. Theinterfibrillar region between the microfib-rils was also well observed from themicrographs. Removal of the cementingmaterials, i.e hemicelluloses and lignin,was evident from the FTIR results.Crystallinity index increased with thetreatment but the extent of improvementafter 1 hour of treatment was limited bydegradation of cellulose chains and thefiber cell wall. The AFM results showedthat the fiber surface roughnessdecreased due to the alkali treatment.

AbstractThis paper presents a case study on theperformance of Tunnel Boring Machine(TBM) opted for the construction of theInterstate Raw Water Transfer (ISRWT)project currently constructed in Selangor-Pahang, Malaysia. The performance ofTBM is affected by various properties ofrock mass such as the strength of rock,the occurrence of fault zone, the joint ori-entation and the existence of a waterbearing zone. In this project, the 44 kmInterstate Raw Water Transfer tunnel isdesigned to cross solid rock along thealignment with the overburden rangesfrom just several meters at each portal tomore than one thousands meters at thecentre of the tunnel. Geology of the align-ment comprises of metasedimentary rockat the northern end and granitic rock tothe rest of the tunnel. The method usedfor this study and the evidence are dis-cussed.

IntroductionThe growing concern of water shortage inthe western states of Peninsular Malaysiaincludes Selangor, Kuala Lumpur andPutrajaya due to the expanding popula-tion and booming economy has initiatedthe idea of channeling water from Pahangto Kuala Lumpur via a tunnel. In this proj-ect, the Malaysia Government proposedthe construction of the 44.6 km longInterstate Raw Water Transfer (ISRWT)tunnel that will transfer water fromSemantan River to the heart of KualaLumpur. The tunnel will channel rawwater from the Semantan River, near toKampung Jambu Rias, at the northeastpart of Kuala Lumpur through the MainRange to the Hulu Langat, Selangor nearto Kuala Lumpur where the water will betreated before piped to the consumers.The Interstate Raw Water Transfer tunnelis designed, for the first time to crosssolid rock of the Titiwangsa Main Rangegranite along the alignment with the over-burden ranges from just several meters ateach portal to more than one thousandmeters at the centre of the tunnel.Geology along the alignment comprises ofmetasedimentary rock at the northernend and granitic rock to rest of the tunnel.Generally, the Titiwangsa Main Range

at tunnel level throughout the route withsome part of the Karak Formation,,Semantan Formation and Jelebu SchistFormation, thus highly variable of tunnelface condition was expected to encounterthroughout the 44 km construction of thetunnel. The tunnel is designed to be con-structed in two different methods of con-struction with 70% of the alignment willbe constructed using TBM whilst the final30% of the line will be using the NewAustrian Tunnelling Method (NATM). Thepurpose of this study is to investigate theeffect of rock mass condition on TBM per-formance.Geology of the areaThe geology along the tunnel route is pre-dominantly the Main Range granitebatholith with a lesser extent of meta-sedimentary rocks of the Karak Formation(Fig. 1). The depth of the tunnel rangesfrom 25 m to 1315 m below the groundsurface as it passes through the MainRange. These zones intruded into thePaleozoic clastic and calcareous metased-iments Pitfield et al., 1990). The graniticrocks along the proposed tunnel route canbe divided into 3 types: first is the KualaLumpur Granite; second is the GentingSempah Microgranite and third is theBukit Tinggi Granite. Geochronologicalstudies indicate that the granitic rockswere emplaced during Late Triassic. TheKongkoi Fault separates the Kuala LumpurGranite from the Genting SempahMicrogranite and has a metasedimentaryscreen on its west flank. Similarly, theGenting Sempah Microgranite is separat-ed from the Bukit Tinggi Granite by theBukit Tinggi Fault. There is a systematicrelationship between the joints, flowstructures, geometry of the granite plu-tons, dykes and faults.

Specification of TBMThree identical 5.2 m diameter open typeTBMs are opted in tunnelling through thehard rock Titiwangsa Main Range Granite.Each of the TBM is designed to bore thefirst 11.670 km, second 11.670 km andthird 11.218 km respectively. The follow-ing Table 1 gives a brief sum-mary of thetechnical specification of the TBM used inthe project.

Research methodologyThe effect of rock mass quality on theperformance of TBM is studied from tun-nel distance (TD) 0 to 3000 m. Studieswere carried out based on the analysis ofthree different data collected at the tun-nel site, first is the daily tunnel mappingrecord, second is the TBM performancedata and third is the lab test results ofUCS on rock samples cored for every 50m of the tunnel. The daily mapping of thetunnel rock mass records the strength ofintact rock, joints properties and ground-water condition. The evaluation on theperformance of TBM was made based onfew parameters such as boring energy,rate of penetration (ROP) and rate perminute (RPM).

Affect of rock formations on TBMperformanceThe selection of open type TBM was madeconsidering the geological condition ofthe proposed alignment such the hardrock of Titiwangsa Main Range Granite.The granitic rock had experienced seriesof faulting and folding (Shu, 1969 &Stauffer, 1968). Few difficult excavationsby the TBM were envisaged due to theexistence of fault zones, high overburdenand potential risk of crossing water bear-ing zones. In Karak site, TBM-1 is mostunexpectedly encountered few locationsof high water bearing zones. One of thelocations is at CH8, 143 (TD1322) ofapproximately 10 ton/min (av-erage of4.1 ton/min) of sudden inrush warmwater was recorded, fig. 2. At this exactlocation, TBM recorded 46.50 N/mm2 ofboring energy, 7.10 rev/min of RPM and0.80 m/h of ROP. It was unexpected con-

dition as the three parameters of TBMshowed constant rates of reading until it’ssuddenly hit the water pocket zone.Another encountered was at CH9, 939(TD3118) to CH10, 019 (TD3198), whereappximately 10.7 ton/min of warm waterat temperature 33°C inrush into the tun-nel from highly fractured, smooth planar,closely to medium spaced joints, orientedat N180°/70°-80°. The rock mass condi-tions were generally good, classified asrock class CII to D, based on JapaneseHighway system of rock mass classifica-tion.

Whilst in TBM-2, high water ingress andface collapse are the recorded geologicalproblems encountered. The first majorwater ingress occurred at CH27, 962(TD2200) ~ CH27, 402 (TD2760), whereapproximately 5.4 ton/min of water gush-ing into the tunnel system. The secondinccident occured at CH30, 066 (TD95.2m), water ingress was recorded at 5ton/min (average 1.8 ton/min), believeddue to the occurrences of highly fracturedzone of Kongkoi Fault, positioned atCH31, 200. Tunnel face collapses wereencountered at few points of TBM-2 withmajor collapse occurred at CH 28, 591(TD 1571m) and this is believed due tothe existence of Lepoh Fault (CH28, 600).But, the collapse started to occur after theTBM passed the zone with the collapsingof loose rocks onto the TBM and createda chimney shape of hole with 50 m high

and 5 m wide above the TBM. There are many models and equationsdeveloped in estimating the performanceof TBM ahead of the boring. In many ofthe models, UCS value of rock is the mostparameter used, eventhough the usage ofUCS solely may not provide accurateresults (Cigla et. al., 2001 & Yagiz, 2006).In this project, UCS values were recordedfor every 50 m of the tunnel in addition tothe daily reading of Schimdt Hammerrebound value, fig. 3a. The two testsshowed a satisfactory correlation as therebound hardess values deacreased withthe decreasing value of UCS, particurlalyat TD800 and TD 2100 – 2500. A similarpattern is also seen in boring energy anddaily progress of TBM, fig. 3b. There wereslightly dropped of boring energy anddaily progress of TBM at TD800 and

TD2100. As shown in fig. 3(a & b), excavation atTD 2100-2250 (Joint orientation =N180°E /80°) showed high grade rockthat required high type of support systembecause the presence of sheared zone offresh rock. Boring energy is low sincethere was favourable oriented of frac-tures, whereas water ingress was veryhigh at more than 300 liter/min whichweaken the rock into smaller pieces andcaused the excavation progress per day ishigh.

Discussion and conclusionThe performance of TBM, thus the costscheduling and time of project comple-tion, is greatly affected by the geologicalconditions and discontinuity properties ofrock mass. Unexpected high wateringress and poor rock mass conditionsmay reduce dramatically the averageprogress rates and practical conse-quences. Part of the problems wereexpected to occur looking at the previousgeological records and preliminary verticaldrilling carried out prior the project. But,most of the time, the ground is still unex-pectedly delivers problems towards theprogress of tunnelling.

Introduction

TitaniumTitanium has extraordinary propertiessuch as high bio-compatibility with highcorrosion resistance compared to othermaterials. Because of these properties,titanium is mainly used as the basic mate-rial for medical equipments. Other thanthat, as one of the lightest material thatcan be applied in metals, titanium is alsowidely used as the basic material in air-craft industries.Pure titanium has a relatively low density;4.51g/cm3, high melting point; 1941[K]with Young’s Modulus of 10.43 ×104[MPa]. Titanium possesses aHexagonal Close Packed (HCP) structurewhich is alpha-phase (α-phase) below1155±2[K]. Titanium with HCP crystalstructure is known as α-Titanium. On theother hand, above 1155±2[K], titaniumpossesses a Body Centered Cubic (BCC)structure which is beta-phase (β-phase).Titanium with BCC crystal structure isknown as β-Titanium[1]

Strengthening MechanismYield strength(σy) for most of the materi-als vary by the grain size, according to theequation known as Hall-Petch equation

shown below:

Where d is the average grain diameterwhile σ0 and ky are constants for a partic-ular material. This equation shows theinverse proportion relation between theaverage grain diameter and the yieldstrength; means that smaller grain sizewill gives higher yield strength[2]. Severe Plastic Deformation (SPD) is themain method to produce Ultra Fine Grain(UFG), structure of metals with muchimproved strength and hardness[3,4].There are various types of SPD procesesincluding Equal Channel Angular Process(ECAP)[4], High Pressure Torsion(HPT)[5], Accumulative Roll-Bonding(ARB)[6] process, etc. However,Mechanical Milling (MM) process was usedin our laboratory to carry out the SPDmethod. MM process is a powder process-ing technique that involves fracturing andwelding of powder particle in high energymilling machine[7]

Harmonic Microstructure“Harmonic microstructure” is a term usesto define a hetero-mesh microstructure ofmaterials, where fine grains structureformed at the surface region of the pow-der; known as “shell”. On the other hand,coarse grain structure formed at the inte-rior region of the powder is known as“core”. For instance, previous researchproved that harmonic microstructure ofStainless Steel (SUS316) has 1.5 timeshigher intensity ratio and 3.0 times high-er ductility ratio than conventional materi-als[8].“Shell” and “core” region are usuallyformed after the powder undergoes theMM process. After sintering process, themilled powder will form a compact metalwith continuous shell and core region.The combination of MM and sinteringprocess is called Severe PlasticDeformation-Powder Metallurgy (SPD-PM)process. Figure 1 shows the harmonicmicrostructure design; with shell and coreregion at the surface and inner part of thepowder respectively.

Experimental Procedures

Mechanical MillingCP titanium powders were mechanicallymilled by jet mill equipment known asNano Jetmizer NJ-50 with zirconium coat-ed layer inside the main chamber. Theprocessing capacity is from 10 to 1[kg/hr]with 0.6~1.0[m3/min] airflow. The millingprocess was done at room temperature innitrogen, N2 gas atmosphere. Table 1shows the details of milled powder.

SinteringCP titanium powders were sintered by DRSINTER SCM 2000 SPS machine. The pro-cessing temperature was set to 973[K]and the load was set to 50[MPa] for0.6[ks]. Then, the sintered compactswere left cooled inside the SPS machinefor 1.8[ks] before the samples were takenout.

Results & DiscussionFrom Fifure 2, by comparing the threetypes of powder’s appearances, it can benoted that jet milled A powder has round-ed shape with bumpy surface while theinitial powder did not show any clearbumpy surface. This shows that jet milledA powder has been deformed by jetmilling process.From Figure 3, the jet milled A powderhave different sizes of grains within thepowder particles; where smaller grainsformed around the surface region (shell)whereas bigger grains formed around thecenter region (core). On the other hand,jet milled A powder and the initial powderdid not show any differences in the grainsize. The grains have irregular shape.These micrographs reveals that jet milledB powder formed shell and core regionafter jet milling process. On the otherhand, jet milled A and initial powder didnot form any clear shell and core region.

Figure 4 shows SEM micrographs of initialand jet milled A SPS compacts. From themicrographs, it can be noted that grainsin jet milled A were smaller compared tothe initial compact. At the surface of theparticle, a thin layer of shell region couldbe seen although grains inside the shellregion could not be clearly seen.These micrographs reveals that the shellregion appeared after the powder under-goes deformation through jet millingprocess under jet milled A condition.

Figure 5 shows the increasing in of aver-age hardness value from initial to jetmilled A SPS compact. This was due tothe decreasing of the total grains sizes asthe pressure of jet milling processincrease.Figure 6 shows the average, maximumand minimum values of dynamic hardnessfor initial and jet milled A SPS compacts;shell and core region. From the initial SPS

compact, it can be noted that there werenot much different in dynamic hardness

values between shell and core region.This shows that UFG did not form in theinitial powder particles, resulting in noshell region within the consolidated com-pact. However, from jet milled A SPS compact,it can be noted that there were large dif-ference between dynamic hardness val-ues of shell and core region which is 286HT. This shows that the shell region is farharder than the core region.

Furthermore, for jet milled B SPS com-pact, the maximum and minimum hard-ness values measured in shell region areover than 800 HT and not below than 300HT respectively. However, the maximumand minimum hardness values measuredin core region are below than 500 HT andover 100 HT respectively. This shows thateven in core region, the nearer the inden-tation spot to the shell region, the harderthe material become.From both of the histograms, it can benoted that the hardness values of eachshell and core region increased from ini-tial to jet milled A SPS compact. The UFGformed through jet milling process, whichcan lead to the formation of shell andcore network after they are being consol-idated by sintering process.

ConclusionsCP titanium low oxygen powders (TiLOP)were mechanically milled by jet millingprocess. The powders then were consol-idated by Spark Plasma Sintering (SPS)process. Microstructure and hardness ofconsolidated compacts were investigated.Based on the experimental results, thefollowing conclusions could be obtained. 1.Powders milled by jet milling processhave smaller grains than the initial pow-ders. The higher the air flow pressure, thesmaller the grains became.2.Consolidated compacts fabricated withhigh air flow pressure jet milled powdersshowed a thin layer of shell region with-out clear grain boundaries can be seenwithin the region.3.High air pressure jet milled compact hasa higher hardness values compared withthe initial compact.4.The shell region showed higher hard-ness value than the core region.5.Jet milling process did improve thehardness of powders and their consolidat-ed compacts by forming ultra fine grains.Increasing the air flow pressure during jetmilling process will increase the thicknessof the shell region and the hardness ofthe powders and their consolidated com-pacts. However, the problem where cleargrains cannot be seen within the shellregion should be studied in the future

Novelty and inventivenessPorous medium stove with cogenerationis a new design of porous burner fordomestic use. By using a ceramic porousmaterial as medium of combustion, thecombustion efficiency increased. Theincreased in combustion efficiency indi-cate the reduction of combustion pollu-tants such as carbon monoxide (CO) aswell. Furthermore, the novelty of thehexagonal shape of the stove ease theuse of Thermoelectric (TE) cells for electrical cogeneration by using heat dissipa-tion at the burner wall. Thus, more heatconvert to electrical power to be useddirectly for mobile phone charging. Thisleads to the increased of thermal efficien-cy of the stove.Usefulness and applicationThe porous medium stove (PMS) withcogeneration is never been developedand still not available in the market so far.This stove consist of porous medium (alu-mina and coated with silicon carbide) pro-vide lower emissions especially CO andNOx, lower fuel consumption (up to 50%fuel saving) compare to the conventionalstove, gives better thermal efficiency andhigher flame temperature. The currentprototype of PMS can be used eitherindoor or outdoor applications. The PMSalso able to be used with different fuelssuch as LPG (indoor) and butane (out-door), including extra feature with cogen-eration for mobile, torch light, radio andbattery charging. The thermoelectric cellshave been used in this cogeneration pur-poses.Market and commercial potentialNowadays, manufacturers are looking fora better option on combustion device,especially for domestic use. Most domes-tic stove in the market use gas fuel suchas LPG, methane, propane or butanefrom fossil fuel derivatives. This hydrocar-bon fuels price increased due to globalconsumer demand and the depletion ofthe fuel itself. A highly efficient PM stovehas been developed to reduce the usageof HC fuels without compromising on its

performance and value for money.Environmental FriendlinessEmissions from the PM stove were underacceptable levels and compliant withANSI standards. The present stove isenvironmentally friendly and can also beused in generation of electric power andis particularly useful in outdoor activitiessuch camping and travel.

How Nanocoat works?NANOCOAT kills bacteria by inhibiting thegrowth of microorganisms by emittingoxygen radicals that penetrate and dis-rupt their cell walls. When the cell wallsare penetrated, leakage of metabolitesoccurs and other cell functions are dis-abled, thereby preventing the microor-ganism from functioning or reproducing.In terms of the effect against fungi, theNANOCOAT solution inhibits the cell fromsplitting under mitosis.

ApplicationsMost importantly, our NANOCOAT solu-tion is designed to be easily integratedinto any surface (wood, tiles, polymer,and fabric) with good adherence. Wehave proven the functionality of thismaterial in the following projects:∗Rapid KL public transport∗Setia Alam City Mall∗Gleneagles Hospital∗Little Mandarin House – Kindergarten

The novel process that was adjudged tobe of Gold Award merit during ITEX 2013is for the production of a cancellous-typeartificial bone replacement (the finalproduct being named as TCP.COM –TriCalcium Phosphate Composite). Theprocess starts off with the fabrication analpha-TCP (tricalcium phosphate) scaffoldthrough a proprietory method of directlysintering CaCO3 and CaHPO4.2H2O at acertain temperature. The scaffold wasthen coated with poly ɛ-caprolactone(PCL) through a special dipping process.The final composite obtained retained athree dimensional fully-interconnectedporous structure similar to human cancel-lous bone. The coated alpha-TCP scaffoldexhibited high porosity with large poresize (500–700 µm) that can be consid-ered to mimic the cancellous bone struc-ture.The compressive strength of the

alpha-TCP composite improved signifi-cantly upon PCL coating, i.e. an enhance-ment of 25 times as compared to thatbefore coating. In vitro biological evalua-tions have proven that bone marrow cellsadhered and proliferated well on the com-posites. Based on these findings, it can besafely concluded that the process is suc-cessful in producing alpha-TCP scaffoldscoated with bioresorable PCL which is ofgood potential to be used as cancellous-type artificial bone replacement.
