Abstract
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. Keywords: Design of Experiments, Dynamic Mechanical Analysis, Epoxy, Luffa Cylindrica, Silicon Carbide
Highlights
Over past few decades, polymer composites are preferred over conventional materials
Influence of SiC Particulates on Dynamic Mechanical Response of Treated Luffa Cylindrica Epoxy Composites done to improve its toughness, brittleness, wear etc. they are reinforced with natural fibres
Luffa Cylindrica fibres are treated for optimality and are used as reinforcements with Epoxy to determine mechanical strength
Summary
Polymer composites are preferred over conventional materials. These composites are used in many applications due to ease of processing, productivity, decrease in cost etc. Some of the natural fibres used to prepare polymer composites are sisal, hemp, jute, flax, banana, palm, coir, kenaf, Luffa Cylindrica etc. These fibres are available in abundance, biodegradable, recyclable and possess appreciable mechanical strength. Epoxy is chosen as matrix material with natural fibres as reinforcement due to its diverse and unique characteristics. Epoxy exhibits comparatively many advantages over other resins like thermoset and thermoplastics namely minimum cheaper and abundant, shrinkage during curing, good moisture and chemical resistant, long shelf life, good mechanical strength etc. Fillers can be used for further enhancing its properties and manufacture high performance engineering materials[1]
