This document specifies the conditions for determination of the stress-rupture time diagram of continuous fibre-reinforced ceramic matrix composites (including carbon fibre-reinforced carbon matrix composite) at high temperature in air, vacuum and inert gas atmospheres under constant tensile loading.
This document applies to all ceramic matrix composites with continuous fibre reinforcement: unidirectional (1D), bidirectional (2D) and tridirectional (xD, with 2 < x ≤ 3), loaded along one principal axis of reinforcement.
NOTE 1 In most cases, ceramic matrix composites to be used at high temperature in air are coated with an antioxidation coating.
NOTE 2 Since the main purpose of the test is to obtain the stress-rupture time data, the deformation measurement is not mandatory.
