Understanding Mechanical Behavior of Kevlar Polymer Hybrid Composites : A Review

Abstract

A review of mechanical properties of Kevlar and different artificial based fibers/fillers/particles or nanotubes reinforced composites forming polymer hybrid in different capacities was carried out. Most of the composites were prepared by hand layup, compression and injection molded techniques. Many of the review works has concentrated on using Scanning electron microscopic analysis to be followed in order to evaluate surface morphology of the composites respectively. Normally the relationship between theoretical and experimental values was figured out using rules of mixture in the present papers studied for review. Mainly out of the analytical results showed good agreement with the experimental results. From the review, in Kevlar based composites, it is observed that, hybrid composites showed good results in terms of Impact strength, tensile strength, flexure strength, fracture toughness good energy absorption capacity, and compression after impact properties. The use of surface treatment or coupling agents have helped in improving the strength, adhesive, high strain properties in the materials. The use of fillers, particles, nano-tubes or nano clays has really enhances the Kevlar based polymer materials properties.
