CFCCARBON LTD can produce all kinds of 3D C/C composite material with stable and reliable quality. We can produce all kinds of C/C composite Aircraft brakes/ disc/ Disks. With different 2.5D or 3D structures. 3D C/C composite material has advantages of long lasting lifetime, low competitive costs, more clean…
For 3D C/C composite material, we can produce with density of 1.7-1.9g/cm3, others as per customers’ requests.
What is 3D C/C composite? Its with 3 directions of carbon fibers, x,y,z directions. Sometimes we call 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.
Standard properties of 3D C/C composite material are as following:

Note: We can do X-RAY tests and other tests.
Names of the material: CFC, Carbon composite, C/C, carbon fiber composite, carbon carbon composite, carbon reinforced carbon, carbon fiber reinforced carbon, carbon carbon.
Production process: first, we use carbon fiber, or graphite fiber to make a special shape, then we use the ways of CVI, or CVD, or other way to increase the density. the production takes a long time, about 5-8months due to different size product.
C/C composite material features:
(1) Physical properties: After high temperature treatment, the C/C composite has higher carbon content, >99%, the density is low, the mechanical properties are good. Due to good characteristic of high melting point of carbon, high temperature resistance, corrosion resistance and thermal shock performance, the carbon composite is resistant to acid, alkali and salt.
(2) Mechanical properties: C/C composite has good mechanical properties of the strength and elastic modulus, good wear and tear resistance.
(3) high-temperature stability: The room temperature strength of carbon composite can keep up to 2500 ℃, is not sensitive to the thermal stress, and the ablation resistance performance is good.
(4) Comprehensive performance evaluation: C/C composite has good strength and elastic modulus at room temperature; less production processes of C/C composite material can save materials and manufacturing costs, and its more safety and reliability.
We can produce with all shapes of 3D C/C composite material as per customers’ special request.
