%X The compressive strength of C/SiC composite at different strain rates, off-axis orientations and after high-velocity impact was studied. The compressive strength was found to be 137£¿¡À£¿23, 130£¿¡À£¿46 and 162£¿¡À£¿33£¿MPa at a strain rate of 3.3£¿¡Á£¿10£¿5, 3.3£¿¡Á£¿10£¿3, 3.3£¿¡Á£¿10£¿3 s£¿1, respectively. On the other hand, the compressive strength was found to be 130£¿¡À£¿46, 99£¿¡À£¿23 and 87£¿¡À£¿9£¿MPa for 0¡ã/90¡ã, 30¡ã/60¡ã and 45¡ã/45¡ã fibre orientations to loading direction, respectively. After high-velocity impact, the residual compressive strength of C/SiC composite was found to be 58£¿¡À£¿26, 44£¿¡À£¿18 and 36£¿¡À£¿3.5£¿MPa after impact with 100, 150 and 190£¿m/s, respectively. The formation of kink bands in fibre bundles was found to be dominant micro-mechanism for compressive failure of C/SiC composite for 0¡ã/90¡ã orientation. On the other hand, delamination and the fibre bundles rotation were found to be the dominant mechanism for off-axis failure of composite
