ISO 22459-2020 精细陶瓷(高级陶瓷、高级工业陶瓷)--陶瓷复合材料的增强--在环境温度下多丝束中纤维断裂时的拉伸强度和拉伸应变分布的测定 Fine ceramics (advanced ceramics, advanced technical ceramics) — Reinforcement of ceramic composites — Determination of distribution of tensile strength and tensile st

This document specifies the conditions for the determination of the distribution of strength and
rupture strain of ceramic filaments within a multifilament tow at room temperature by performing a
tensile test on a multifilament tow.
This document applies to dry tows of continuous ceramic filaments that are assumed to act freely and
independently under loading and exhibit linear elastic behaviour up to failure. The outputs of this
method are not to be mixed up with the strengths of embedded tows determined by using ISO 24046 .st edition 2020-06 Fine ceramics (advanced ceramics, advanced technical ceramics) — Reinforcement of ceramic composites — Determination of distribution of tensile strength and tensile strain to failure of filaments within a multifilament tow at ambient temperature Céramiques techniques — Renfort de céramiques composites — Détermination de la distribution de la résistance en traction et de la déformation à la rupture en traction de filaments dans un fil multifilamentaire à température ambia
