Experimental Investigation of Coconut Coir Ash and Rice Husk Composites

Natural fibers and fillers from renewable resources are emerging as sustainable alternatives to synthetic materials in polymer composites. This study focuses on developing hybrid composites using coconut coir ash as the filler and rice husk as the fiber, with epoxy resin as the matrix. The research investigates the mechanical behavior of the hybrid composites, particularly under impact, flexural, tensile, compression, and hardness loads. Test results indicate that these hybrid composites outperform conventional single glass fiber- reinforced composites. The findings highlight the potential of natural hybrid reinforcements for eco-friendly and high- performance composite applications.
