Carbon Carbon Composite Aircraft Brake Discs

Carbon carbon composite materials are carbon matrix reinforced with carbon fibers. They have the advantages of low density, high strength, high specific modulus, high thermal conductivity, low expansion coefficient, and good friction performance. Most of them are used in aviation brake discs (Vice), rocket nozzles, and some aircraft brake control system.

What is Carbon Carbon Composite Material?

Carbon carbon composite material, usually abbreviated as C/C or CFC, is a type of composite material made primarily of carbon fibers and carbon matrix. It is known for its exceptional mechanical, thermal, and chemical properties.

The composite is made by impregnating carbon fibers with a carbon-rich resin or pitch, followed by a heat treatment process known as carbonization. During carbonization, the material is heated to very high temperatures in an inert atmosphere, which converts the resin or pitch into a pure carbon matrix. This process eliminates any remaining impurities and strengthens the material.

Carbon carbon composites are high strength, low weight, and excellent resistance to heat and corrosion. They have a high thermal conductivity and low coefficient of thermal expansion, making them suitable for applications in high-temperature environments. They are commonly used in aerospace, automotive, defense, and sporting goods industries, where lightweight and high-performance materials are required.
