High-purity carbon-based composite material
The invention discloses a high-purity carbon-based composite material which is characterized in that a framework of the high-purity carbon-based composite material is a carbon fiber preform formed by netted tire, carbon fiber cloth, winding, lamination and radial needling, high-temperature purification treatment is performed after rapid vapor deposition, and finally a layer of compact pyrolytic carbon coating is deposited on the surface to prepare the high-purity carbon-based composite material. The high-purity carbon-based composite material disclosed by the invention is high in purity, excellent in mechanical property and good in heat conduction and frictional wear performance; the high-purity carbon-based composite material is small in surface porosity, corrosive gas can be prevented from rapidly permeating into the material, the service life of the material is prolonged, the advantages of cost and performance of the carbon-based composite material are both considered, and the use requirement of an N-type single crystal thermal field is met.
本发明公开了一种高纯炭基复合材料，其特征在于，所述高纯炭基复合材料的骨架为网胎‑碳纤维布‑缠绕‑叠层径向针刺的碳纤维预制体，通过快速气相沉积后经高温纯化处理，最后在表面沉积一层致密的热解炭涂层制备而成。本发明公开的高纯炭基复合材料纯度高、机械性能优异、导热和摩擦磨损性能佳；该高纯炭基复合材料表面孔隙率小，能阻止腐蚀性气体快速向材料内部渗透，延长材料的使用寿命，实现碳基复合材料兼顾成本和性能的优势，满足N型单晶热场的使用需求。
