Title

THE INVESTIGATION ON COMPOSITES PRODUCED USING POLYLACTIC ACID/WHEAT STRAW FIBERS TREATED WITH SILANE

Pages

  207-219

Abstract

 In this paper, the properties of POLYLACTIC ACID (PLA) / wheat straw fiber composites manufactured using twin screw extruder and compression molding were studied. Wheat straw fibers were treated with trietoxymethel silane to produce better compatibility between two phases. Physical and TENSILE PROPERTIES of the composites were measured and analyzed. The effect of the wheat straw fibers on the thermal properties of composites was determined using DSC techniques. The effect of silane treatment on the wheat straw fibers was analyzed by FTIR. Scanning electron microscopy of composite samples surface were used to study water absorption and thickness swelling. Composites made using treated wheat straw fiber showed significantly lower water absorption and thickness swelling than composites made using PLA/ untreated wheat straw fibers. The lower amount of water absorption and thickness swelling occurred in the pure PLA composites. The cracks and break occurred at the surface of PLA/ untreated wheat straw fibers composites after immersion in the water indicating higher water absorption and thickness swelling. The treated wheat straw fibers due to better wetting and better bonding at the interfacial layer with PLA matrix showed higher TENSILE PROPERTIES compared with PLA/ untreated wheat straw fiber composites. DIFFERENTIAL SCANNING CALORIMETER test showed that with the addition treated wheat straw fibers to PLA increased glass transition temperature. The nucleating effect of wheat straw fibers, special treatment with silane increased in the crystallization temperature of composites compared to PLA which is a positive effect on the degree of crystallization.
