This Part of ENV 658 specifies the conditions for the determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement, (under three-point br four-point loading) at ambient temperature.
The method applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (ID) bidirectional (2D), and tridirectional (3D), with weak reinforcement in the third direction.
NOTE. The method should not be used to obtain absolute values of flexural strength for design purposes.
