Fine ceramics (advanced ceramics, advanced technical ceramics) — Physical properties of ceramic composites — Guidelines for determination of void and fibre contents in polished cross section by image analysis

Abstract / scope

This document describes the methods for the determination of void and fibre with specific orientation contents in a polished cross section of continuous fibre-reinforced ceramic matrix composites by image analysis.

The methods apply to all ceramic matrix composites with continuous fibre reinforcement: bidirectional (2D) and tridirectional (3D).

The methods also apply to carbon-fibre-reinforced carbon matrix composites (also known as: carbon/carbon or C/C).

NOTE            The result obtained by the method is not volume content but area content.
