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.
4d carbon fiber composites
CFCCARBON LTD is a group company, specializing in the production of 4D carbon carbon composite. We can design and produce parts due to special applications of 4D CC composite.
For the carbon carbon 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.
4D Carbon carbon composite features:
(1) Physical properties: After high temperature treatment, the carbon 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 carbon composite is resistant to acid, alkali and salt.
(2) Mechanical properties: carbon carbon 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 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: carbon carbon composite has good strength and elastic modulus at room temperature; less production processes of carbon carbon composite material can save materials and manufacturing costs, and its more safety and reliability.
