Multilayer biocomposites of PLA woven fabric and PBS sheets using compression molding process

Abstract

AbstractBiocomposite materials play an important role to replace the conventional polymer composites in the issue of serious environmental problems from the end‐used products. The relationship between the design and construction of biocomposites structure and their properties is an important factor to the composite application. In this study, the biocomposites of poly(butylene succinate) (PBS) reinforced with poly(lactic acid) (PLA) woven fabric to improve mechanical properties of PBS matrix was fabricated by compression molding process. The plain weave PLA woven fabrics showed higher tensile strength (28.9%) and modulus (21.5%) than the twill 2/2 weave pattern. However, the flexural strength and modulus of composites reinforced with multi‐layers PLA woven fabric are higher than the one‐layer reinforcement (57% and 31%, respectively). The impact and peel strength of PLA twill 2/2 weave biocomposite are higher than the plain weaving. The mechanical property of matrix reinforced with plain structure was found to increase on the vertical axis while the twill weaving showed the increase on horizontal axis adhesion between the reinforced PLA woven fabric and the PBS matrix.
