摘　　要：为了研究C/C材料快速致密的工艺,采用常压炭化和高压炭化联合致密的纯沥青液相炭化工艺,对叠层针刺C/C材料进行致密化处理,使预制体密度由0.48 g/cm3增至1.92 g/cm3,对该材料的力学及热学性能进行了测试,与整体毡C/C材料性能进行了对比,并利用扫描电子显微镜观察了材料的显微结构。结果表明,该材料具有较好的力学与热学性能,微观结构界面结合良好。The material of nappe prickly were prepared by constant pressure and high pressure carbonization.The density of this material was increased from 0.48 g/cm3 to 1.92 g/cm3.The performances of this material were tested,and orientation of microstructure was studied under SEM.The results indicate that the material has fine performances and the interface is well combined and the compact technical route is feasible and reasonable.
