摘要:
为了探究增密工艺对 C/C-Cu 复合材料组织和性能的影响，分别采用化学气相渗透( CVI) 和先驱体浸渍 裂解转化( PIP) 对 2. 5D 针刺碳毡进行增密处理，得到由热解碳和树脂碳填充的 C/C 增强体，采用真空浸渗工艺 制备了 C/C-Cu 复合材料，并对其进行了组织分析和性能测试。结果表明: 采用 CVI 增密制备的 C/C-Cu 复合材 料中 TiC 界面层更薄，热解碳对碳纤维起到了较好的保护作用，垂直、平行方向的电阻率分别为 0. 72、0. 63 μΩ·m、 压缩强度分别为 367. 61、326. 87 MPa，抗拉强度为 62. 54 MPa，其导电性能、压缩强度、抗拉强度以及塑性均优于 PIP 增密，破坏机制为纤维拔出破坏; 采用 CVI 增密制备的 C/C-Cu 复合材料硬度值为 77. 28 HBW，略低于 PIP 增 密( 81. 59 HBW) ，但二者差异较小。综上，CVI 增密工艺更适合用来制备 C/C-Cu 复合材料的 C/C 增强体。
Abstract:
In order to explore the effect of densification process on the microstructure and properties of C /C-Cu composite，the 2. 5D needle-punched carbon felt was densified by chemical vapor infiltration ( CVI) and precursor impregnation pyrolysis ( PIP) to obtain C /C reinforcements filled with pyrolytic carbon and resin carbon，respectively． C /C-Cu composite was prepared by vacuum infiltration process，and the microstructure analysis and performance test were carried out． The results showed that the TiC interface layer in the C /C-Cu composite prepared by CVI process was thinner，and the pyrolytic carbon had a better protection effect on the carbon fiber． The resistivity and compressive strength in the vertical ( parallel) direction were 0. 72 ( 0. 63) μΩ·m，367. 61 ( 326. 87) MPa， respectively．And the tensile strength is 62. 54 MPa． Its electrical conductivity，compressive strength，tensile strength，and plasticity were better than those of PIP process． The failure mechanism was fiber pull-out failure． The hardness value of C /C-Cu composite prepared by CVI process was 77. 28 HBW，which was slightly lower than that of PIP process ( 81. 59 HBW) ，but the difference between them was small． In conclusion，the CVI densification process was more suitable for the preparation of C /C reinforcements of C /C-Cu composites.
