Mechanical properties of a hybrid composite material (epoxy-polysulfide rubber) reinforced with fibres

摘要

This study investigated the mechanical properties of a hybrid polymer matrix composite material (PMCs) prepared from 98 wt% epoxy resin and 2 wt% polysulfide rubber reinforced with two types of fibres, glass fibres and carbon fibres, which were used in the form of a plain woven material with a volumetric fracture of 20%. Mechanical tests were conducted for the composite materials before and after reinforcement with these fibres to ascertain the effect of adding fibres on the mechanical properties of the composite material. The fibre effect was evident in improving all studied properties, especially tensile strength and impact strength.
