What is 2D carbon carbon composite? Its only 2 directions of the fibers. mainly x, y directions in the plane direction. Most of the time, the product is produced by carbon fiber cloths, stick together layer by layer, such as carbon composite boards, carbon composite sheets, carbon composite U, L profiles for heaters…
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.
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 composite is resistant to acid, alkali and salt.
(2) Mechanical properties: 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 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 composite has good strength and elastic modulus at room temperature; less production processes of carbon composite material can save materials and manufacturing costs, and its more safety and reliability.
Special Properties of carbon carbon composite: High Acid-resisting and alkali-resisting properties; Low density compared to metals; High temperature, cold-resistant, tensile strength is 7-9times than Steel; very good thermal shock resistance…
