Evaluation of tensile properties on Glass/Carbon/Kevlar fiber reinforced hybrid composites

Abstract

Composites made of synthetic fiber combined hybrid composites are find many industrial applications. Due to high strength to light weight ratio, higher modulus significantly reduced cost. In this research, composite fiber in woven mat form is added to matrix element with varying stacking sequences of symmetrical laminates. Four various hybrid laminate composites having glass, kevlar and carbon fibers are the reinforcements in varying stacking sequences are produced using hand lay-up technique followed by compression molding. The mechanical strength of the produced composite is evaluated. Experimental results found that composite having stacking sequences of Carbon-Kevlar- Carbon-Kevlar- Carbon (C-K-C-K-C) has the highest value of tensile strength 385.09 MPa respectively. Scanning Electron Microscope (SEM) is used to examine the morphology of fractured surface of hybrid composites during testing. SEM images revealed that hybrid composite with C-K-C-K-C had less defects on its fractured surface compared to other counter parts of the hybrid composites.
