Tensile strength tests have been carried out on composites consisting of an epoxy matrix with pretensioned filaments of several different materials. The results are compared with the non-reinforced matrix material and, with the exception of steel wire reinforcement, favourable results are obtained for the composites. A theoretical analysis which assumes linear elasticity gives good agreement with experimental results, but this agreement is improved by compensating for pre-load relaxation and resin contraction during the cure. © 1984.
