The Effect of Blending Ratio on Mechanical Properties of Polylactic Acid (PLA) / Ethylene Vinyl Acetate (EVA)

Abstract:

The objective of the study is to improve the mechanical properties of Polylactic acid (PLA)/Ethylene Vinyl Acetate (EVA) blend. The blend was prepared via twin screw extruder and compression molding with different composition. The effect of different blend ratio on the mechanical properties was investigated by Tensile and Flexural test. The mechanical properties of PLA shown an improvement compared to the pure PLA with the incorporation of EVA. The flexural modulus increased with the increased of EVA content, while the tensile and flexural strength also increased when EVA increased. The optimum tensile and flexural strength was at 90PLA/10EVA of blends ratio.
