Physicomechanical Properties, Machinability, and Morphological Behavior of Short Glass Fiber-reinforced Nylon 6 Composites

Abstract

In this study, a series of short glass fiber-reinforced nylon 6 composites with different weight ratios of glass content viz., 15, 30, 40, and 50% have been fabricated by melt mixing. The fabricated nylon 6 composites have been characterized for physicomechanical properties such as specific gravity, tensile properties, and wear resistance. A marginal improvement in tensile strength and tensile modulus is observed with increase in high modulus fiber. Wear resistance is increased with the increase in rigid glass fiber content in the nylon matrix. The dimensional stability of the composite is improved with the increase in fiber content. The acoustic behavior of these composites has been measured using acoustic emission technique. The surface morphological behavior of the composites has been investigated by scanning electron microscopy (SEM). The SEM micrograph reveals fiber pullout and skin formation in the composites.
