EXPERIMENTAL INVESTIGATION OF MECHANICAL BEHAVIOUR OF GLASS-EPOXY COMPOSITES

This paper reports on the manufacturing of the glass fibre reinforced epoxy composite laminate as per the ASTM (American Society for Testing and Materials) Standards. This laminate consists of matrix and reinforcement. Epoxy is used as a structural matrix material which is then reinforced by glass fiber, combining glass fibres with resin matrix results in composites that are strong, lightweight, corrosion-resistant and dimensionally stable. They also provide good design flexibility, high dielectric strength and act as inflammable materials. Their tremendous strength-to-weight and design flexibility make them ideal in structural components for the aerospace industry.
In this paper the glass fibre reinforced epoxy composite is manufactured into six different parts each having ratios of glass fibre to epoxy resin as 0:100, 20:80, 40:60, 60:40, 80:20, 100:0 respectively and are compared for ultimate tensile strength, impact strength and flexural strength of the material by conducting experiment such as tensile test, flexural test and impact test.
