Annex A (informative) Examples of types of rupture

This document specifies the conditions for determination of the inter-laminar shear strength of ceramic matrix composite materials with continuous fibre reinforcement for temperatures up to 2 000 °C under a vacuum, or a gas atmosphere, which is inert to the material under test, by loading of notched specimens in compression.

NOTE 1The use of a vacuum or a gas atmosphere is aimed at avoiding changes of the material to be tested due to chemical reaction with its environment during the test.

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 2Care should be exercised in interpreting the results of the test method to obtain absolute values of the inter-laminar shear strength of ceramic matrix composites for design purposes.
