摘要

The mechanical properties of woven cloth with two sizes of carbon tows reinforced silicon carbide composites were investigated by tension, shear and bending tests. The experimental results show that the composite fabricated with signal tows possesses greater stiffness and strength than the composite with large tows. Unequal tow size Caused differences of the warp waviness and the void volume fraction in the composites, which led to differences in rnechanical properties of composites.
