CFCCARBON LTD is a group company, specializing in the production of carbon carbon composite| C/C composite material. We can produce 2.5D C/C composite with stable and reliable quality. We can produce all kinds of C/C composite Aircraft brakes/ disc/ Disks. 2.5D C/C composite material has advantages of long lasting lifetime, low competitive costs, more clean…
For 2.5D C/C composite, we can produce with density of 1.7-1.9g/cm3, others as per customers’ requests.
The price of 2.5D carbon carbon composite is different due to different applications, and different density. If with lower density, the price will be lower; if with higher density, the price will be higher. We can produce and design for the material due to different applications, and we can make special adjustment for special property.
What is the 2.5D carbon carbon composite? Its based on the 2D carbon composite, and has some fibers between the layers of carbon cloths. Its 3directions, but the z direction has less fiber. We call it 2.5D.
The main application of 2.5D carbon carbon composite is to produce airplane brakes. Its specially designed for airplane brakes. Carbon / carbon composite material is a porous brittle material, afraid of wet, afraid of oil, fear of oxidation, fear of bruising, fear of bruising, fatigue, compared to Steel, Therefore, carbon composite brakes have their own characteristics of the use of maintenance.
The main features of carbon-carbon brake discs
1). Carbon-carbon brake disc density is 1 / 4-1 / 5 of steel. Because the brake weight is lighter than steel about 40%. The Aircraft performance improved significantly.
2). The Specific heat, thermal expansion coefficient is small, high strength stable at high temperature, so deformation and melting will not occur.
3). Friction and wear performance is good. The use of wear and tear is about 25% -50% of steel. Ordinary military machine has life of 1000 times ups and downs, the civil aircraft up to 3000 times ups and downs. Carbon-carbon brake discs wear to the limit size, you can also renovation.
