摘要

The main aim of the proposed research is to study properties of Polyhydroxybutyrateco-rnvalerarate (PHBV) based green composites reinforced with lignin based carbonrnfibres. In order to understand the mechanism of carbon fibre-matrix interaction andrnprocess engineering during composite fabrication, commercial carbon fibre were usedrnin this piece of investigation to extend the developed research on to lignin basedrncarbon fibres. The advanced biocomposites from carbon fibre and PHBV bioplasticrnwere prepared with extrusion compounding and injection molding techniques. Therneffects of fiber length and fiber loading, on the performance of PHBV/carbon fibrerncomposites were studied. The mechanical properties such as tensile and flexuralrnstrength/modulus of the composites significantly increased with the fibre length asrnwell as fibre loading. The thermomechanical behavior such as heat deflectionrntemperature (HDT) and storage modulus of the composites were determined byrndynamic mechanical analysis (DMA). HDT values of the composite materialsrnincreased with the carbon fibre loading and fibre length. The DMA results reveal thatrnthe storage modulus of PHBV/carbon fibre composites was higher when compared tornthe matrix. Scanning electron microscopy (SEM) was used to observe the adhesionrnbetween fibre and matrix. The tensile modulus of the composites were evaluatedrntheoretically by Hirsch model.
