Preparation method of movable disc for aircraft brake
The invention discloses a preparation method of a movable disc for an aircraft brake. The preparation method specifically comprises the following steps of 1, ceramic treatment, 2, preparing a carbon-carbon porous body, 3, preparing a C/C-SiC movable disc body, and 4, performing anti-oxidation coating treatment on the non-friction surface. A carbon fiber needled felt is subjected to ceramic treatment through a polynitrogen silane solution, ceramic components in the carbon fiber needled felt are densified through a precursor impregnation and pyrolysis process, after a C/C-SiC disc body is obtained, anti-oxidation coating treatment is conducted on a non-friction surface, and the C/C-SiC movable disc having the characteristics that the dynamic balance amount is small and the friction performance of a ceramic material is not attenuated under a wet working condition can be obtained. The hardness and the size of the movable disc are both lower than those of a traditional ceramic material, and the movable disc is free of noise and shaking when being in friction with a pressing disc, a static disc and a pressure-bearing disc made of a carbon-ceramic composite material.
本发明公开一种飞机刹车用动盘的制备方法，具体包括以下步骤：步骤1：陶瓷化处理；步骤2：制备碳碳多孔体；步骤3：制备C/C‑SiC动盘体；步骤4：非摩擦面防氧化涂层处理。通过聚氮硅烷溶液对碳纤维针刺毡进行陶瓷华处理，再将其内部陶瓷组分通过先躯体浸渍裂解工艺进行增密，得到C/C‑SiC盘体后，对非摩擦面防氧化涂层处理，得到不仅具有C/C复合材料动平衡量小的特点，而且具有陶瓷材料湿态工况下摩擦性能不衰减特性的C/C‑SiC动盘；该动盘硬度和尺寸均低于传统陶瓷材料，与碳陶复合材料制备的压紧盘、静盘、承压盘对摩无噪音、无抖动。
