Abstract / scope
This document specifies a method for the determination of the tensile strength, tensile modulus of elasticity and strain at the maximum force of a resin-impregnated yarn specimen at ambient temperature. This method is applicable to yarns of ceramic fibres that are used as reinforcements in composite materials. The test results obtained by this method are applicable for quality control and comparison of the ceramic fibres.
The outputs of this method are not comparable to the strength of filaments derived from tensile tests on dry tows specified in ISO 22459.
