ANALISYS OF MECHANICAL BEHAVIOUR FOR COMPOSITES BASED ON KEVLAR FIBRES

Abstract

Composite materials emerged as a substitute for classic materials from the desire to offer manufacturers other raw materials, with superior properties, that are easier to materialize. By designing them according to the requirements, the properties of these raw materials are clearly superior to those of each component taken separately acting that synergy like that of teamwork. Often, strong materials are relatively dense; also, increasing strength or stiffness generally results in a decrease in impact resistance. Kevlar has a network of hydrogen bonds between the polymer chains that give it great stiffness. This study focuses on the mechanical proprieties of Kevlar fiber based composites that can replace standard materials in various products.
