Abstract : The effects of fiber volume content, fiber-matrix bond, heat treatment, and age hardening on the transverse mechanical properties of unidirectional aluminum matrix fibrous composites have been investigated. Test results have indicated that the increase of the matrix strength is directly responsible for the increase of the transverse strength of a composite fabricated under heat-treated conditions, as compared with the corresponding strength for the annealed condition. The composite transverse tensile strength and elastic modulus have been calculated by using the finite-element method and the von Mises-Hencky criterion. Both the square and hexagonal arrays have been considered for the fiber configuration in the matrix. The analytical results are compared with the experimental data obtained at room temperature and low strain rate. (Author)
