Detailed description
Our company can produce 4D and 5D carbon carbon composite (CC composite) with stable and reliable quality. We can produce all kinds of carbon-carbon composite with different 4D structures, different types with resin, pitch based, CVD, CVI… For 4D C/C composite, we can produce with density of 1.5-1.95g/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.
