Fine ceramics (advanced ceramics, advanced technical ceramics) — Mechanical properties of ceramic composites at high temperature — Determination of stress-rupture time diagram under constant tensile loading (ISO 19604:2018)
This document specifies the conditions for determination of the stress-rupture time diagram ofcontinuous fibre-reinforced ceramic matrix composites (including carbon fibre-reinforced carbonmatrix composite) at high temperature in air, vacuum and inert gas atmospheres under constant tensileloading.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 principalaxis of reinforcement.NOTE 1 In most cases, ceramic matrix composites to be used at high temperature in air are coated with anantioxidation coating.NOTE 2 Since the main purpose of the test is to obtain the stress-rupture time data, the deformationmeasurement is not mandatory.
