| Abstract: | D carbon fiber_reinforced silicon carbide composites were manufactured by LPCVI. Effect of carbon interphase thickness on the properties of C f/SiC m composites was studied. It is shown that composites with higher strength and fracture toughness can be achieved by selecting appropiate interphase thickness. The behavior of stress_displacement and fracture mode of composites differ with the interphase thickness. |
