Mechanical Characteristics of Chitosan Dispersed Poly Lactic Acid/Basalt Fiber Hybrid Composites

This paper focus on mechanical characterization of Chitosan (CS) particles dispersed Poly lactic acid (PLA) reinforced basalt fiber (BF) hybrid composites. Hybrid composites with different weight percentage of PLA, BF and CS were prepared by solid state reaction blending (SSRB) in twin screw extruder and specimens were prepared by injection moulding technique. The properties of injected moulded composites were extensively examined by tensile test, flexural test, and impact test. It was found that the increased weight percentage of basalt fibers and chitosan particles in poly lactic acid exhibits good mechanical properties. It is demonstrated in this paper BF and CS were will incorporated and uniformly distributed using Scanning electron microscopy. The optimum weight percentage of BF and CS in PLA composites was found to be 25 wt% and 10 wt% respectively.
