摘　　要：为实现民用客机碳刹车盘组件的国产化,开展碳刹车盘组件的研制工作。本文采用整体针刺毡+化学气相沉积(CVD)工艺制备该型飞机碳刹车盘,其平均密度达到1.769g/cm3,高于国外OEM样件。整体针刺毡结构的引入,使碳刹车盘的力学性能要明显优于国外OEM件,提高了刹车材料及飞机的安全性。同时,该碳刹车材料摩擦性能的离散性小于国外OEM件,在刹车过程中冲击力较小,提高了飞机的操稳性,延长了起落架的寿命。In order to realize the localization of carbon brake disc components of a certain type of passenger aircraft,AVIC Xi'an Aviation Brake Technology Co.,Ltd.carried out the research and development.Combined with Chemical Vapor Deposition(CVD),the integral needle-felt was used to fabricate the aircraft brake disc.The average density was 1.769g/cm3,mechanical properties was better than foreign carbon brake disc,and the safety was improved.Meanwhile,the dispersion of friction properties was less than that of foreign carbon brake disc.The impact was smaller during braking,that was improved the stability of the aircraft and extended the life of the landing gear.
