摘要：
In this paper we have studied the influence of discontinuities on elastic and mechanical properties of composite materials reinforced with woven Carbon, Carbon-Kevlar and Kevlar. In addition, we have studied the way variations of the volume proportion of reinforcement influences elasticity modulus and tensile strength for the studied composite materials. In order to appreciate the property difference between different areas of the composite material and also the dimensions of the defective areas, a relative uniformity influence coefficient was introduced offering us a tool for assessing the mechanical behaviour of the studied composite compared with a reference composite. We have also performed experimental validations of the obtained theoretical results.
