Carbon Fiber Auto Parts Antioxidant Performance To Improve The Means Of What Two?

1, improve the graphitization degree of carbon fiber auto parts, so as to improve the oxidation resistance of carbon fiber auto parts,
2. Coating on the surface of carbon fiber auto parts to protect carbon fiber auto parts.
3, improve the oxidation resistance of C/C material matrix; The oxidation resistance of C/C material matrix can be improved by adding oxidation inhibitors. For example, phosphorus compounds can make oxygen lose its oxidation activity through the action of phosphorus and oxygen, so as to achieve the purpose of antioxidant, but the effect is not ideal. Another method is to add antioxidant components in the matrix, such as heavy metals, ceramics, etc., can improve the oxidation resistance of C/C composites, and can also add organosilicon, organotitanium, etc., in the matrix, so that the matrix C is replaced by SIC and TIC can also achieve the purpose of oxidation resistance. Generally speaking, the internal antioxidant method can only solve the oxidation protection problem of C/C composites below 1000℃, and the solution of the oxidation problem at higher temperatures also needs to be combined with other antioxidant technologies.
