Static and dynamic tensile tests were performed on unidirectional born/aluminum composites and cross-ply laminated plates. Static and dynamic stress-strain curves were obtained and the effect of the strain rate of the tensile strength was investigated. The 0゜ and laminated specimens showed no strain rate sensitivities regarding tensile strength : but in the case of the 45゜ and 90゜ specimens, the tensile strength increased as the strain rate increased. The previously proposed constitutive equations for unidirectional fiber reinforced metals were modified to take into account the strain rate controlled uniaxial tensile tests. The calculated results were compared with the experimental results. It was confirmed that the proposed constitutive equations gave a reasonable prediction of the stress-strain curves.
