Method for producing carbon-carbon composite material blank for airplane brake disc
The invention provides a method for producing a carbon-carbon composite material blank for an airplane brake disc. The method comprises the following steps: performing chemical vapor infiltration on carbon brake disc preforms (4) by using carbon source gas in a CVI furnace, stacking the carbon brake disc preforms into a cylindrical stock column during charging, and paving vegetable parchment between any two adjacent layers of carbon brake disc preforms; and during ventilation, carbon source gas is divided into two paths to reach the stock column from bottom to top, wherein one path leads to the inner surface of the stock column, and the other path leads to the outer surface of the stock column. The method provided by the invention is helpful for improving the content of pyrolytic carbon in the rough layer in the carbon-carbon composite material green body, so that the product quality consistency is improved.
本发明提供了一种生产飞机刹车盘用炭‑炭复合材料坯体的方法，该方法包括在CVI炉(1)内以碳源气体对炭刹车盘预制体(4)进行化学气相渗透，装炉时炭刹车盘预制体堆叠成圆筒状的料柱，任意相邻两层炭刹车盘预制体之间铺有硫酸纸；通气时碳源气体分两路由下而上到达料柱，其中一路通往料柱的内表面，另一路通往料柱的外表面。本发明提供的方法有助于提高炭‑炭复合材料坯体中粗糙层热解炭的含量，进而提高产品质量一致性。
