摘要

The transtropic T300 carbon unidirectionally fiber-reinforced composites based on three isotropic matrices (Epoxy, LY556, 8511-7) are numerically and analytically studied. Their physical and mechanical characteristics are evaluated with the Chamis analytical method depending on the fiber volume content and type of the matrix. The dynamics and strength of cylinders made of such materials under internal explosion are numerically investigated. The highest cylinder strength at the identical volume content is provided by the 8511-7 matrix, while the lowest by the Epoxy matrix. The cylinder strength monotonically increases with increasing the volume content. At the identical volume content and load, the cylinder strength with different matrices differs significantly, while the dynamics differs insignificantly.
