Comparative Study of Thermal Property (HDT) of Hybrid Composites Prepared using Glass Fiber, Sugarcane Bagasse and Human Hair

The main aim of this research work is to prepare hybrid composites and to compare them on the basis of thermal property namely Heat Deflection Temperature (HDT). For preparation of composites, hand lay-up method is used. Unsaturated polyester (UP) resin is principal binding material (50wt %) while Cobalt naphthenate is used as an accelerator (0.5wt %) and Methyl ethyl ketone peroxide (MEKP) is used as a hardener (1wt %). 400 gsm chopped strand mat of E- glass fiber is primary reinforcement material while sugarcane bagasse and human hair fiber waste are used as additive fiber in glass fiber reinforced plastic (GFRP) for preparing hybrid composite. An exothermic reaction occurs in which energy released is more than the energy supplied, this extra energy in the form of heat is due to formation of new bonds by cross-linking. Post curing, prepared composites are evaluated on Heat Deflection Temperature (HDT).
