Investigation of Tensile and Burning Rate Behavior of Hybrid Glass-Semicar bon Fibers/Epoxy Composite

In this research, the hybridization effect of Semic arbon fibers (SCFs) with glass fibers on tensile pr operties and burning rate of composites as compared to glass fibers reinforced e poxy matrix composite was investigated. In this reg ard, four plies composites with different arranging of SCFs and glass fibers w ere fabricated by hand lay-up method. The hybridiza tion of SCFs with glass fibers was caused reducing tensile strength and ela stic modulus of these composites as compared to gla ss fibers reinforced composite. But the failure strain of these composit es was improved. Also, the obtained results showed that both failure strain and tensile strength have important role on energy abso rption in composites that the effectiveness of thes e factors proportionate SCFs and glass fibers ratio. The results of rate and the cross section of burning showed that with increasi ng SCFs to glass fibers ratio, the flame retardancy of composite increases.
