Fabrication, Tensile and Bending Properties of Wheat Straw/Polylactic Acid Green Composites

Abstract:

Polylactic Acid (PLA) and raw Wheat Straw (WS) were used to fabricate WS/PLA green composites. By hot-press process, WS/PLA composites with different WS volume fractions (20% and 30%) were obtained. The experimental results showed that when the WS volume fraction was 20%, the composites had a tensile strength of 23.68MPa and modulus of 1.47GPa; bending strength of 64.13MPa and modulus of 1.44GPa. When the WS volume fraction increased to 30%, the tensile strength and modulus enhanced by 45.18% and 35.37% respectively; bending strength and modulus increased by 15.80% and 25.69%. It was indicated that PLA can be successfully reinforced by WS at certain volume fractions.
