Degradation in Tensile Properties with Overlapped and Discontinuous Fabric Preforms

Measured tensile properties including the modulus, strength and elongation of resin transfer molded composites, which were fabricated using several fabric preforms through the normal, overlapped and discontinuous models, were compared. As expected, the overlapped and discontinuous models had lower tensile modulus and strength than the normal model; these values were functions of the effective fiber-volume fraction. The differences were examined...
