Summary
This document specifies a method for determining the interlaminar shear strength at room temperature, by compressing a double-notched specimen, and another method for determining the interlaminar shear strength and shear modulus at room temperature by the Iosipescu essay. This document applies to all ceramic matrix composites reinforced with continuous fibers, having unidirectional (1D), bidirectional (2D) and multidirectional (xD, with x > 2) fiber architecture, with the majority of the reinforcement being made up of a stack of strata. This document applies to the development and comparison of materials and to the assurance of quality, characterization, reliability and production of design data. The simpler method of testing a double-notched specimen for compression is only applicable when shear strength is to be measured.
