Preparation method of carbon-carbon blank for carbon-ceramic brake disc
The invention provides a preparation method of a carbon-carbon blank for a carbon-ceramic brake disc. Thepreparation method comprises the following steps: step A, loading annular carbon fiber preforms into a vapor deposition furnace for pre-deposition, separating the carbon fiber preforms by carbon-material packing paper during furnace loading and stacking, respectively forming an inner ring space and an outer ring space on the inner side and the outer side of a stock column by baffles, wherein a bottom inlet of any one of the outer ring space and the inner ring space is blocked, and a top outlet of the other one is blocked; B, taking the carbon-carbon blank obtained through pre-deposition out of the vapor deposition furnace and then carrying out surface turning; and C, putting the carbon-carbon blank obtained through surface turning into the vapor deposition furnace to be subjected to densification treatment, wherein the furnace charging structure is the same as that in the step A, and the blocking modes of the outer ring space and the inner ring space are determined according to the distribution situation of the density of the carbon-carbon blank in the radial direction. The preparation method provided by the invention is beneficial to improving the density uniformity of the carbon-carbon blank, so that the carbon-ceramic brake disc can be produced more smoothly.
本发明提供了一种碳陶刹车盘用炭炭坯料的制备方法，包括以下步骤：步骤A，将圆环形的炭纤维预制体装入气相沉积炉内进行预沉积，装炉堆叠时，炭纤维预制体由碳素材料的垫纸隔开，料柱的内、外两侧分别由挡体形成内环空间和外环空间，外环空间和内环空间中任意一者的底部入口被封堵，另一者的顶部出口被封堵；步骤B，将预沉积得到的炭炭坯料从气相沉积炉取出后进行表面车加工；步骤C，将表面车加工得到的炭炭坯料装入气相沉积炉内进行致密化处理，装炉结构与步骤A相同，但外环空间和内环空间的封堵方式根据炭炭坯料的密度在径向上的分布情况而定。本发明提供的制备方法有利于提高炭炭坯料的密度均匀性，从而确保碳陶刹车盘能够更顺利地生产。
