CFCCARBON LTD is a group company, specializing in the production of carbon carbon composite| C/C composite material. We can produce all kinds of 3D C/C composite for different applications. We can produce all types of 3D C/C composite with stable and reliable quality. 3D C/C composite material has the advantages of low competitive costs, long lasting lifetime, more clean…
For 3D C/C composite, we can produce with density of 1.4-1.95g/cm3, different 3D CC composite structures. others as per customers’ requests.
The price os 3D carbon carbon composite varies due to structures, densities… IF the structure is easy, the price of the raw structure will be cheap; if the structure is complex, then the cost of structure is high.
The price of 3D carbon carbon composite is different due to different applications, and different density. If with lower density, the price will be lower; if with higher density, the price will be higher. We can produce and design for the material due to different applications, and we can make special adjustment for special property.
What is 3D carbon carbon composite? Its with 3 directions of carbon fibers, x,y,z directions. Sometimes we call
3D-xyz-structure
it 3D xyz structure. See structure attached. Another type of 3D carbon structure is 3D hoop structure: with fibers in axial, radial and hoop directions. There are also other types of 3D structures. See bellow drawing too.
CFCCARBON LTD is a professional manufacturer of carbon composite. With max density up to1.9-1.95g/cm3. We can produce carbon composite with required structures and required properties.
