Development of Euphorbia Latex and Bamboo Fiber Based Green Composite.

Abstract

Novel composites with improved mechanical strength, thermally stability and better biodegradability were fabricated using polyester resin (PR) and euphorbia coagulum (EC) with natural bamboo fiber (BF) by a compression molding technique. The addition of EC makes the composite more pronounced for alkali-treated BF. The composites were characterized in terms of water absorption, mechanical, thermal and biodegradability. Composites showed considerable improvement in thermal stability, mechanical properties (flexural strength and impact strength) and biodegradability. EC modified composite shows maximum improvement in physico-mechanical properties compared to other composites. The inoculation of EC modified and unmodified composite with fungi resulted in higher growth on modified composite compared to unmodified composite. These novel composites could be labeled as sustainable material because they were prepared from low-cost BF and EC through a green approach. The composite material developed can be used in building constructions as wood substitution, automotive parts, sports goods, etc.
