Embedded carbon-ceramic brake disc and preparation method thereof
The invention discloses an embedded type carbon ceramic brake disc which comprises a composite disc body and a silicon carbide column, the composite disc body is a carbon-carbon composite material which is obtained by densifying a carbon fiber preform and composed of deposited carbon and carbon fibers, and a plurality of embedding holes are formed in the disc face of the composite disc body; the silicon carbide columns are embedded into the embedding holes through graphite columns, and molten silicon permeates into the composite disc body under the vacuum high-temperature condition and reacts with the graphite columns to generate the silicon carbide columns; meanwhile, the molten silicon reacts with the deposited carbon to generate silicon carbide, and a carbon ceramic material composed of the carbon fibers, the silicon carbide, the remaining silicon and the remaining graphite is formed on the disc face of the composite disc body.
本申请公开了一种镶嵌式碳陶制动盘，包括复合盘体与碳化硅柱，所述复合盘体为碳纤维预制体增密得到的由沉积碳与碳纤维组成的碳碳复合材料，所述复合盘体的盘面上设置有若干个镶嵌孔；所述碳化硅柱由石墨柱镶嵌入所述镶嵌孔内，在真空高温条件下，将熔化的硅渗透至复合盘体内，与石墨柱反应生成碳化硅柱；同时熔化的硅与沉积碳反应生成碳化硅，在复合盘体的盘面形成由碳纤维、碳化硅、剩余硅以及剩余石墨组成的碳陶材料。
