Advanced technical ceramics - Ceramic composites - Methods of test for reinforcements - Part 7: Determination of the distribution of tensile strength and of tensile strain to failure of filaments within a multifilament tow at high temperature
This European standard specifies the conditions, apparatus and procedure for determining the distribution of tensile strength and tensile strain to failure of ceramic filaments in multifilament tows at high temperature in air, vacuum or a controlled inert atmosphere.This part of EN 1007 applies to tows of continuous ceramic filaments, which are assumed to act freely and independently under loading and behave linearly elastic up to failure.Two methods are proposed depending on the temperature of the ends of the tow:a) hot end method;NOTE 1 The application of the hot end method is restricted by ceramic glues with sufficient shear strengths at the test tempera
