Carbon Composite Tube

The fatal weakness of ceramics is that they are extremely brittle and very easy to break. They are also very sensitive to small defects such as cracks, pores, and inclusions. Using carbon fiber to reinforce ceramics can effectively improve toughness, change the brittle fracture morphology of ceramics, and prevent cracks from spreading and expanding rapidly in the ceramic matrix.

Carbon/carbon composites are advanced composites. This completely artificially designed and manufactured composite material composed of pure carbon elements has many excellent properties. In addition to high strength, high rigidity, dimensional stability, oxidation resistance, and wear resistance, it also has high fracture toughness and pseudo plasticity. Therefore, it is widely used in high-tech fields such as missile warheads, solid rocket engine nozzles, and aircraft brake discs.

Carbon fiber reinforced metal matrix composites are composite materials with carbon fiber as reinforcing fiber and metal as matrix. The main technical difficulty in manufacturing carbon fiber reinforced metal matrix composites is the surface coating of carbon fiber. When preparing carbon fiber reinforced metal matrix composites, the surface modification of carbon fiber mainly adopts vapor deposition, liquid sodium method, etc., but due to its complex process and high cost, the promotion and use of carbon fiber reinforced metal matrix composites have been limited..

Adding carbon fiber to the cement matrix makes carbon fiber-reinforced cement-based composites (CFRC), also known as fiber-reinforced concrete. Adding high-strength carbon fiber to cement-based materials is an important measure to improve the crack resistance, impermeability, shear strength, and elastic modulus of cement composites, control crack propagation, improve strong alkali resistance, and enhance deformation capacity.
