Carbon-carbon composites offer a unique combination of properties. In non-oxidizing environments, they retain room temperature mechanical properties at>2225C. For applications in oxidizing environments, current coatings limit maximum use temperature to about 1600C. High thermal conductivity and low thermal expansion of carbon-carbon composites make them excellent candidates for applications involving thermal shock.
Because of variety of carbon fibers, weaving patterns, and lay-up procedures that can be used for carbon-carbon composites, their mechanical properties can be tailored over a wide range to fit the application.
Continuing research on carbon-carbon composite materials emphasizes an understanding of material behavior. Of particular importance to both researchers and fabrication personnel are methods of improving matrix properties (particularly in-plane shear and out-of-plane tensile strengths) and improving oxidation-resistant coating with higher use temperatures, longer lifetimes, and less costly fabrication methods.
CFCCARBON LTD is a factory of carbon carbon composite, which is government owned. We have set up a research and development team, some of which has more than 45 years of research experience in research institute of China in the carbon composite material field, vigorously carried out application research and secondary development of special military technologies and focused on solving low-cost preparation and batch production problems of products.
