What is a ceramic matrix composite (CMC)?

The reinforcements used in ceramic matrix composites (CMC) serve to enhance the fracture toughness of the combined material system while still taking advantage of the inherent high strength and Young’s modulus of the ceramic matrix.

Who is CMC materials?

CMC Materials (formerly Cabot Microelectronics) is a supplier of critical materials to semiconductor manufacturers and pipeline operators.

What is CMC in aerospace?

This unique association of materials revolutionized the aerospace industry, making parts more resistant to extreme conditions and lighter compared to the previous technologies. CMC materials prevail over most of the drawbacks of conventional technical ceramics, which are low fracture toughness, limited thermal shock resistance & brittle failure.

Are CMCs brittle?

They consist of ceramic fibres embedded in a ceramic matrix, forming a ceramic fibre-reinforced material. Although their constituents are brittle, CMCs are tough due to the effective design of the fibreImatrix interface, which arrests and deflects cracks in the matrix, preventing failure of the fibrous reinforcement.
