his research work aimed to study the effects of the addition of sisal fiber and surface treatment by epoxy silane on the physical and thermal properties of polylactic acid (PLA). Specimens of PLA and unidirectional fiber-reinforced composite were processed by a compression molding machine and evaluated the physical and thermal properties by water absorption measurement and differential scanning calorimetry (DSC) analysis respectively. The result showed that water absorption tended to increase by adding sisal fiber whereas surface treatment of sisal fiber by epoxy silane improved water resistance of composites. The water absorption values at immersion time of 5 days were 0.89 1.13 and 1.26 % for PLA PLA/treated sisal fiber composite and PLA/untreated sisal fiber composite respectively. For thermal properties the addition of sisal fiber led to decreases in glass transition temperature and crystallinity. These were because the presence of continuous fiber might interfere with the crystallization of PLA. The surface treatment of continuous fiber with epoxy silane led to difficult crystallization. The good interfacial adhesion interrupted PLA alignment.

The objectives of this research were to study cellulose fiber extraction from rice straw with sodium hydroxide in various conditions (with 5 1 0 and 1 0 % of sodium hydroxide at room temperature 60ºC and 90 ºC for 0.5 1 2 and 3 hours) and to study rice straw nonwovens preparation by the wet-laid process. Oil wicking ability oil absorption ability air permeability morphology and physical properties of prepared nonwovens were investigated. It was found that the optimal condition for cellulose fiber extraction from rice straw was 5% of sodium hydroxide at 90 ºC for 2 hours. At this condition the cellulose fiber yield of 2 2% and the fiber length of 1 . 9 6 cm were obtained. The oil wicking ability and oil absorption ability of rice straw nonwovens increased when weight per unit area increased. Therefore oil absorbed into gaps between fibers of the nonwovens by capillary effect. Moreover the nonwovens could wick and absorb virgin palm oil better than fried palm oil because virgin palm oil has a lower viscosity than fried palm oil. The viscosity increased from derived lipid and other substances which dissolve and disperse increasing after frying food. The results indicated that the rice straw nonwovens had oil absorption ability.

This research was resulted of the characterization of cement paste composites (CPC) blended with palmyra fiber ash and surface-treated on short SWNT prepared by an electroless plating process. The cement paste composites included cement 270 meshes of palmyra fiber ash and short SWNT. The design of experiment was divided into 3 conditions namely uncuring 28 and 56 days in distilled water. The properties of CPC were carried out in chemical composition physical mechanical mineral phase microstructure and statistical analysis. It was found that in the chemical compositions an amount of silicon dioxide aluminium oxide and ferric oxide were 51.53% which was rated in class C. The bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) cured 56-day distilled water were an increased 38%. Then the highest specific electrical resistivity of CPC series PFA5OSWNT0.03 (F) cured 56-day distilled water was 1.14±0.31 mega-ohm.mm. The highest compressive strength of CPC series PFA5AgSWNT0.01 (G) cured at 28-day distilled water was 25.45±2.00 MPa compared with the OPC (A) was an increased 5%. Which the bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) were statistical analyzed the mostly cured at significant difference α = 0.05. In addition CPC series PFA5AgSWNT0.01 (G) mainly contained calcite portlandite quartz dolomite and ettringite were caused increasing compressive strength. And the SEM microphotograph were also displayed the calcium silicate hydrate portlandite and ettringite. Consequently the PFA was used to ability pozzolanic material using for lightweight concrete of CPC.
