scope:

This part of ENV 658 specifies the conditions for determination of compressive properties of ceramic matrix composite materials with continuous fibre reinforcement at ambient temperature. This standard applies to all ceramic matrix composites with a continuous fibre reinforcement unidirectional (1D) bidirectional (2D), and tridirectional (3D), loaded along one principal axis of reinforcement, loaded along the principal axis of reinforcement. This standard does not apply to ceramic composites with a short fibre reinforcement. Two cases are distinguished: a) compression between platens b) compression using special fixture.
