摘　　要：碳/碳(C/C)复合材料是新材料领域重点研究和开发的一类战略性高技术材料。随着C/C复合材料在多个应用领域的不断发展,与之相关的致密化工艺也在发展中逐步深化,多种致密化工艺的混合发展和应用也成为材料领域的研究热点。本文综述了C/C复合材料制备过程中所采用的致密化工艺,详细分析了液相浸渍法和化学气相渗透的工艺原理,并对各种致密化工艺的优缺点进行了对比,最后分析了现有致密化工艺存在的不足,并对C/C复合材料今后的发展做了展望。Carbon/carbon(C/C)composites are a kind of strategic high technology materials which are studied and developed in the field of new materials.With the continuous development and penetration of C/C composites in multiple application fields,the d densification technology related to it is also gradually deepened in the development.The mixed development and application of various densification technologies has also become a research hotspot in the field of materials.In this paper,the densification processes using in the process of preparing C/C composites was reviewed,theories of the liquid phase impregnation and chemical vapor infiltration were also analyzed in detail,the advantages and disadvantages of all kinds of densification technologies were compared.Finally,the defects of the existing densification technology are analyzed,we also forecast the tendency of C/C composites is prospected.
