Scope

This document specifies procedures for determination of the tensile behaviour of ceramic matrix composite materials with continuous fibre reinforcement at elevated temperature in air, vacuum and inert gas atmospheres.
This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bidirectional (2D) and multi-directional (xD, with x> 2), tested along one principal axis of reinforcement or off axis conditions for 2D and xD materials. This method also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C).
NOTE            In most cases, ceramic matrix composites to be used at high temperature in air are coated with an anti-oxidation coating.
