Influence of SiC Particulates on Dynamic Mechanical Response of Treated Luffa Cylindrica Epoxy Composites


Objective: To characterize dynamic response of Epoxy composites reinforced with optimally treated Luffa Cylindrica fibres and Silicon Carbide particulates. Methods: Hand Lay-up technique is used for composite fabrication. Two layer of Luffa Cylindrica fibres and 0% to 7% by weight, as decided by Central Composite Design of Experimental technique, of Silicon Carbide particulates are reinforced. The composites are subjected to Dynamic Mechanical Analysis with temperature ramped from 26°C to 160°C and 1Hz frequency. Findings: About 2300 MPa high storage modulus is noticed within temperature range of 30°C to 70°C. Low loss modulus of 282.35 MPa is observed for composites with 3.5wt% Silicon Carbide at glass transition temperature of 80°C. Improvement: Inclusion of Silicon Carbide particulates has yielded lower damping ratio and higher thermal stability of 95.62°C.
