scope:

This part of EN 658 specifies the conditions for determination of the interlaminar shear strength of ceramic matrix composite materials with continuous fibre reinforcement at room temperature, by loading a notched test specimen in compression. This method applies to all ceramic matrix composites with a continuous fibre reinforcement unidirectional (1D) and bidirectional (2D) and tridirectional (xD, with 2 < x < 3) as defined in ENV 13233, loaded along one principal axis of reinforcement. Two other methods for the determination of shear strength are given in further parts of EN 658.
