    Abstract

    The applicability of ASTM Test Method for Shear Strength of Continuous Fiber-Reinforced Advanced Ceramics at Ambient Temperatures (C 1292) was investigated to determine the shear strength of one-dimensional and two-dimensional continuous fiber-reinforced ceramic composites. The advantages and disadvantages of the test method are addressed, and the effect of notch separation on the measured interlaminar shear strength by the compression of double-notched specimens are discussed. Experimental results are presented for the interlaminar and in-plane shear behavior of two-dimensional Nicalon™/SiC and the interlaminar shear strength of one-dimensional carbon/carbon composites both at room temperature and 1000°C. The effect of fiber coating thickness on the interlaminar shear strength of two-dimensional Nicalon™/SiC is also discussed.
