The tensile strength and associated failure micromechanisms have been characterized for a SiC fiber reinforced ceramic matrix composite subject to strain rates approaching 1000/s. It is found that behavior under such conditions is not described by the current matrix fracture/fiber pull-out models. This is a consequence of the rapid and extreme frictional heating produced at the fiber-matrix interface by sliding velocities on the order of 100 m/s. At sufficiently rapid ...
