NVN-ENV 658-4-1992 Advanced technical ceramics. Mechanical properties of ceramic composites at room temperature. Part 4: Determination of shear strength by compression loading of notched specimens
This Part of ENV 658 specifies the conditions for the determination of the interlaminar shear strength matrix composite materials with continuous fibre reinforcement at ambient temperature, by loading a notched specimen in compression. The method applies to unidirectionally and bidirectionally reinforced ceramic matrix composites, as well as to tridirectional composites with weak reinforcement in the third direction.
NOTE : Two other methods for the determination of shear strength are given in further Parts of ENV 658. The interlaminar shear characteristics can vary significantly depending on specimen preparation and dimensions, rate of application of the test force, surface condition, etc. Comparison of test results is only valid for tests performed under identical conditions.
