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. Our carbon composite airplane brakes are made of this type of material. 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.
Note: We can do X-RAY tests and other tests.
We can produce with all shapes / structures of 2.5D C/C composite as per customers’ special request.
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.
Special Properties of 2.5D 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…
