For the C/C composite, there are so many names of this material, different people use different names when refer to the same product. But its same material.
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 sizes product.
What is 4D C/C composite? Strictly speaking, its 3D CC composite. Its with one more fiber in the plane direction. We call it 4D, which the customer wanted. See attached the drawing and the photos.
4d carbon fiber composites
CFCCARBON LTD can produce 4D C/C composite with stable and reliable quality. We can produce all kinds of C/C composite Aircraft brakes/ disc/ Disks. with 4D. For 4D C/C composite, we can produce with density of 1.4-1.95g/cm3, others as per customers’ requests.
