Glass fibers/SiC p reinforced epoxy composites: Effect of environmental conditions

Abstract

The acceptability of polymer-based composite materials is increasing with time due to superior mechanical and chemical properties. Still, scope of advancement in mechanical behavior of these materials motivated research fraternity to develop new materials. The present article aims to analyze the effect of environment conditions on newly fabricated glass fiber epoxy composites reinforced with variable SiC particles as secondary reinforcement. The evaluation of mechanical strength and effect of environmental conditions on composite performance was analyzed using tensile, compression, flexural, and impact strength testing on universal testing machine. The mechanical strength characterization demonstrated the effect of size and weight fraction of reinforced SiC particles on mechanical strength of composites. The surface morphology of samples was examined by field emission scanning electron microscopy with energy dispersive spectroscopy. Based on mechanical strength evaluation results, an exponential equation was developed to predict the composite life.
