ASPECTS REGARDING THE MECHANICAL CHARATERISTICS OF THE CARBON-KEVLAR COMPOSITE MATERIALS

Abstract

Carbon-Kevlar hybrid composite material structures are used more and more in applications in the automotive, aerospace and military industries. For this reason, to numerically simulate the distribution of stresses and strains in such structures mechanically loaded, it is necessary to know the mechanical properties of such composite materials. It has also become a necessity to know the effects of the hybridization of the two types of fibers (carbon fibers and Kevlar) on the impact properties. For this reason, the article is a short review of the specialized literature regarding the following properties of carbon-Kevlar composites: tensile stress, tensile modulus, flexural strength, flexural modulus, impact properties in impact tests of low speed. Some applications of the plates made of carbon or hybrid carbon-Kevlar composites are highlighted in the last part of the paper.
