Ceramic Matrix Composites (CMC's)
Specimen Preparation (Class 10 Procedures)
Metallographic Class 10 sample preparation


Ceramic matrix composites are used for either their high temperature resistance or there low wear characteristics.

Preparation Challenge:

Specimen preparation of these materials requires that the brittle phases be maintained.
