Carbon-Carbon Composite Specimen Preparation

Metallographic etchant database

Proper preparation of carbon composites is required because the properties of the matrix material and the carbon fibers vary significantly in both hardness and fracture toughness. As a general rule, the most difficult components to prepare in composites are the most brittle components (e.g. carbon fibers). To properly prepare carbon-carbon composites, initial sectioning must minimize damage. Proceeding preparation steps must not result in additional damage.
