The dynamic fiber/matrix interface strength for a silicon-carbide-fiber-reinforced, titanium-alloy metal-matrix composite was measured by impacting the end of a fiber extending through a thin specimen with a diamond-tipped projectile at ~2 m/s. The matrix surrounding the distal end of the fiber was supported on the end of a Hopkinson bar fabricated from hypodermic needle tubing, and an interfer...
