Detailed description

We can supply 4D carbon composite | C/C composite material with stable and reliable quality. We can produce all kinds of C/C composite plates, rods, blocks, pipes, tubes, sheets, moulds, disk/discs… With 3D and 4D structures. 4D C/C has advantages of long lasting lifetime, low competitive costs, more clean…
For 4D C/C composite, we can produce with density of 1.7-1.95g/cm3, others as per customers’ requests.

What is 4D carbon carbon composite? Strictly speaking, its 3D (Three-dimensional structure). All the products are of 3 dimensional structure. What we mean 4D C/C composite is with one or two more fibers in the plane direction. We call it 4D, which the customer wanted. We may produce 5D, 6D…carbon carbon composite, as per customers’ special requirements. The higher the density, the more complex the structures, the higher the prices of CC composite is.

Standard properties of 4D C/C are as following:
