Abstract
The transthickness tensile strength (ITS) of 2-D CVI-SiC/SiC composites reinforced with Tyranno SA or Hi-Nicalon Type-S fibers and various fiber/matrix interphases including single C, dual interphase of SiC and C and multilayer interphase of SiC and C was evaluated by the diametral compression test. The effect of porosity and fiber/matrix interphase on the ITS was evaluated. Specimens failed along an interlaminar plane adjacent to the line of action of the applied load and fractographic analyses revealed that the crack had propagated through matrix pores and along fiber/matrix interphase. It was found that the ITS was affected by porosity significantly. The effect of interphase type and C interphase thickness on the normalized ITS by porosity was discussed.
