Étude comparative du comportement mécanique des matériaux composites à matrice polymère.

Abstract

In this work, we examine the influences of the nature of the reinforcing material and its volume fraction on some mechanical properties of epoxy/glass E, epoxy/glass R, epoxy/carbon HM, and epoxy/carbon HR. In the first step, we examine the influence of the nature of the reinforcement and its volume fraction on the density and porosity of these composite materials. We determine, therefore, the intervals of variation of the volume fraction of the reinforcement. Generating the good, the poor and the poor quality of these composite materials.In the second step, we examine the influences of the nature of reinforcement and its volume fraction on the specific modules of these composite materials, loaded in traction. In a third step, we examine the influences of the nature of reinforcement and its volume fraction on the specific modules of these composite materials, loaded in bending.
