Abstract

Calotropis gigantea fibre has been identified as suitable reinforcement fibre in polymer composites by current researchers. Epoxy matrix provided better interfacial bonding with the fibres and particulates to enhance the mechanical properties of pure polymer substances. If elements such as chitosan, rice husk and red mud have been added in epoxy system, it improves the mouldability and fills the missed portion of fibre reinforcement in composites. Alkaline treatment of natural fibres produce conversion of cellulose and production of short length crystallites which enhances surface roughness on the fibre surface for developing better adhesion between constitution materials of composites. The new variety of natural fibre extracted from stem of Apocynaceae family plant has been used in epoxy matrix along with bio and industrial residues in the present investigation. The three point flexural strength, tensile behaviour and izod impact strength have been evaluated and dimensional stability characteristics are identified for the calotropis gigantea fibre reinforced particulates impregnated epoxy composites.
