Preparation method of high-carbon-yield carbon/carbon composite material brake disc
The invention discloses a preparation method of a high-carbon-yield carbon/carbon composite material brake disc, which comprises the following steps of: stacking annular porous carbon materials to form a material column, placing the material column in the middle of a gas limiting cylinder, placing the material column in a chemical vapor deposition furnace, and performing chemical vapor deposition densification on the porous carbon materials to obtain a carbon/carbon composite material blank; the carbon/carbon composite material blank is subjected to heat treatment and machining to obtain the carbon/carbon composite material brake disc, and the porous carbon material is selected from a carbon fiber preform or a carbon/carbon porous body; according to the preparation method of the high-carbon-yield carbon/carbon composite material brake disc, the gas limiting cylinders, the gaskets, the inner ring gas limiting plates and the outer ring gas limiting plates are reasonably arranged, so that during chemical vapor deposition, the inner ring gas limiting plates and the outer ring gas limiting plates are not prone to falling off, and the high-carbon-yield carbon/carbon composite material brake disc is not prone to falling off during high-carbon-yield carbon/carbon composite material brake disc production efficiency is greatly improved through the reasonable arrangement of the gas limiting cylinders, the gaskets, the inner ring gas limiting plates and the outer ring gas limiting plates. The gas flowing channel is lengthened, so that the carbon source gas is fully utilized, and the carbon yield of the carbon source gas is greatly improved.
本发明公开了一种高碳收率碳/碳复合材料刹车盘的制备方法，将圆环状的多孔碳材料层叠形成料柱并置于限气筒的中间，再置于化学气相沉积炉中，然后再对多孔碳材料进行化学气相沉积增密获得碳/碳复合材料坯料，碳/碳复合材料坯料经热处理、机加工即得碳/碳复合材料刹车盘，所述多孔碳材料选自碳纤维预制体或碳/碳多孔体；沿料柱的高度方向中每200～400mm设置一块限气板，任意两个相邻的多孔碳材料之间均设置有垫片，本发明所提供的高碳收率碳/碳复合材料刹车盘的制备方法，通过限气筒、垫片，内环限气板，外环限气板的合理设置，使得化学气相沉积时，气体流经通道变长，使得碳源气体得到充分的利用，大幅提高了碳源气体的碳收率。
