Scope

This European Standard specifies the conditions for determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement under three-point or four-point bending for temperatures up to 1 700 ℃ in air at atmospheric pressure. This standard applies to all ceramic matrix composites with a 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 The purpose of this standard is to determine the flexural strength of a material under an oxidizing environment but not to measure material oxidation.
