Abstract
The transthickness tensile strength (TTS) of 2-D CVI-SiC/SiC composites reinforced with Tyranno SA fibers was evaluated by the diametral compression test. The effect of specimen size and specimen shape on the magnitude of the ITS were studied and the results were analyzed using Weibull statistics. 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 interfaces between the fiber, fiber coating and matrix. The magnitude of the TTS was found to be independent of specimen size or shape for the range of specimen dimensions investigated, although the amount of scatter was largest for the results obtained from the evaluation of the smallest specimens. The characteristic value of the TTS and the Weibull modulus for the distribution of TTS values were 24.9 MPa and 6.48, respectively.
