Investigation of Flexural Properties of Glass-Kevlar Hybrid Composite

Abstract

Composite materials are attracting huge attention due to their superior properties and being inert to most atmospheric effects. They have high strength to weight ratio and can be moulded into the required shape that can be used for various applications as replacement for metals. This paper consists of study of flexural behaviour of hybrid composite reinforced with woven glass fiber and Kevlar fiber in ply configuration. The three point bending test according to ASTM 790 was performed experimentally on this composite laminate. The fiber volume fraction to matrix volume fraction was taken 40%-60%. The volume fraction of the individual fibers in the composite was varied to determine the effects on the flexural strength of the composite laminate. The laminates prepared were having dimension 80mm X 13mm X 3mm. After testing the H4 configuration had the highest flexural strength of 217.91 MPa also the H2 configuration had maximum flexural modulus. The result of the study can be used for the development of actual composites and simulation purpose.
