Inherent Multi-functions of Green Composties
This paper deals with the development of high strength and functional green composites which are fabricated using starch-based biodegradable resin and hemp fiber. The mechanical characterization of crossply composites was carried out by evaluating both tensile strength and flexural strength as a function of fiber content. It can be seen that the tensile strength of the cross-ply composites was saturated over 50 wt.％ due to the interaction between warp and weft during the hot-pressing. The biodegradation behavior of the hemp fiber reinforced unidirectional composites was also examined by burying them into compost. It is apparent that the natural fiber composites showed an enhanced biodegradation speed. This enhanced biodegradation behavior seems to be derived from increased apparent surface area of the composite specimen due to the preferential biodegradation at interface between hemp fiber and biodegradable resin as well as the preferential water transportation through internal cavity in hemp fiber.
