Full Description

This document specifies a method for the determination of interlaminar shear strength at ambienttemperature by the compression of a double-notched test piece and a method for the determination of interlaminar shear strength and modulus at ambient temperature by the Iosipescu test. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, having unidirectional (1D), bidirectional (2D) and multidirectional (xD, with x > 2) fibre architecture, where a major part of reinforcements is a stack of plies.

This document is applicable to material development, material comparison, quality assurance,characterization, reliability and design data generation. The simpler compression test method of adouble-notched test piece is applicable only when the shear strength has to be measured.
