Advanced technical ceramics - Ceramic composites - Methods of test for reinforcement - Part 4: Determination of tensile properties of filaments at ambient temperature; German version EN 1007-4:2004
This part of EN 1007 specifies the conditions for determination of tensile strength and elongation at fracture of single filaments of ceramic fibre such as tensile strength, Young modulus and stress-strain curve. The method applies to continuous ceramic filaments taken from tows, yarns, braids and knittings, which have strain to fracture less than or equal to 5 %. The method does not apply to check the homogeneity of strength properties of fibres, nor to assess the effects of volume under stress. Statistical aspects of filament failure are not included.#,,#
