21、measurement of tensile properties a of single filament of ceramic fibres at high temperatures in air or inert atmosphere (vacuum or controlled atmosphere). The method applies to continuous ceramic filaments taken from tows, yarns, staple fibre, braids and knitting, that have strain to fracture less
22、than or equal to 5 % and show linear elastic behaviour to fracture. The method does not apply to testing for homogeneity of strength properties of fibres, nor does it assess the effects of volume under stress. Statistical aspects of fibre failure are not included. Two methods are proposed depending
23、on the temperature of the filament end: Hot end method: this method allows determination of tensile strength, of Youngs modulus and of the stress strain curve. NOTE 1 Current experience with this technique is limited to 1 300 C, because of the application temperature of ceramic glue. Cold end method
24、. NOTE 2 This method is limited to 1 700 C in air and 2 000 C in inert atmosphere because of the limits of furnaces. 2 Normative references The following referenced documents are indispensable for the application of this document.
