Carbon-carbon composite material, preparation method and application thereof, and carbon-carbon composite material PECVD bearing frame
The invention provides a carbon-carbon composite material, a preparation method and application thereof and a carbon-carbon composite material PECVD (Plasma Enhanced Chemical Vapor Deposition) bearing frame, and relates to the technical field of carbon materials. Polysilazane is used for enhancing cross-linking between layers of the carbon-carbon bearing frame, cracking between the layers of the material can be effectively prevented, the polysilazane is converted into silicon carbide in the subsequent carbonization process, the mechanical property of the material is remarkably improved, the mechanical property of the carbon-carbon composite PECVD bearing frame manufactured through machining is excellent, the PECVD bearing frame can adapt to the complex PECVD process environment, and the performance of the PECVD bearing frame is improved. And the replacement frequency is low, and the service life is long. Moreover, the resin, the polysilazane and the asphalt are adopted as impregnating materials of the carbon cloth, and compared with other similar net tire needling or Z-direction reinforced plates, the composite material has the obvious advantages of low cost and high preparation efficiency. The carbon-carbon composite PECVD bearing frame prepared by machining the prepared carbon-carbon composite has the advantages of low density, high strength, designable size and the like.
