Degradation analysis of lignocellulosic fillers infused coir epoxy composites in different environmental conditions

India has large resources of natural fibres such as Banana, Khus, Sisal, Korai grass, Talipot, Palm leaf, Coconut, Pineapple, Screwpine, Golden grass, Jute and Sabai among others. In the past, trade of the village folk depended on harvesting fibres grown in their villages. Natural fibers have recently gaining attraction of researchers due to their low cost eco-friendly and biodegradability characteristics they are exploited as a replacement for the conventional fibre, such as glass, aramid and carbon. Use of lignocellulosic fillers offers both cost saving and reduction in density as compared to inorganic particulates. This paper deals with fabrication of composite samples using coconut coir, epoxy resin (with hardener) and lignocellulosic particulate fillers such as cow dung, wheat husk and rice husk. after fabrication composite samples were exposed to different environmental conditions such as ultraviolet radiations, soil burial, high temperature, water (at room and high temperature) to study degradation behaviour of coir fiber reinforced epoxy composites filled with organic lignocellulosic fillers. Composite samples were fabricated using compression moulding technique. Degradation was confirmed by change in mechanical properties (Tensile, flexural and impact strength) and microstructure.
