Poly (lactic acid) fibre reinforced biodegradable composites

This study focuses on the development of fully biodegradable poly (lactic acid) (PLA) fibre reinforced PLA and poly (butylene succinate) (PBS) matrix composites in order to reduce the impact on the environment by long-lasting plastics based composites. PLA self-reinforced composite (SRC) and the PLA reinforced PBS composite (PLA–PBS) composites were produced by film-stacking method. With the increasing of the loading direction fibre content, the composite moduli significantly increase by between 70% up to 6 times higher than those of the matrix films. Higher tensile strength and Young’s modulus have been found in PLA-SRC than in PLA–PBS composite. This is due to better tensile properties of the PLA film and better interfacial adhesion in PLA-SRC.
