Effect of Nano-enhancement on Acacia Wood Bio-composites

Abstract

This chapter explain about nano-enhancement on acacia wood bio-composites. The tensile, flexural and impact tests were describe in this study. The optimum tensile strength was achieved at 10 wt% weight percentage for both U-AW-NCHB-PLA/PHA and M-AW-NCHB-PLA/PHA bio-composites. The optimal flexural strength for AW-NCHB-PLA/PHA bio-composites was achieved at 10 wt% weight percentage for both U-AW-NCHB-PLA/PHA and M-AW-NCHB-PLA/PHA bio-composites. The optimal impact strength for AW-NCHB-PLA/PHA bio-composites was achieved at 10 wt% fiber loadings for both U-AW-NCHB-PLA/PHA and M-AW-NCHB-PLA/PHA bio-composites. Nano-clay enhancement increased the viscosity of the polymer blend, hence increases the threshold mechanical strength of the bio-composites. A strong adhesion was created between fiber and polymer, due to the incorporation of nano-clay, which reduces the agglomeration and formation of void during fabrication. It was observed that the U-AW and NCHB-PLA/PHA has a smooth surface structure and could be considered as semi-brittle/semi-ductile.
