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

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.
