| 摘 要： | 采用４向软编销钉预测体工艺，由ＣＶＩ和ＨＩＰ－石墨化混合工艺及单纯ＣＶＩ工艺制作了Ｃ／Ｃ销钉，并进行了双向剪切强度测试和断面ＳＥＭ观察。结果表明，预制体纤维体积分数越高，则Ｃ／Ｃ销钉的剪切强度越高；微观分析说明混合工艺Ｃ／Ｃ较单纯ＣＶＩ工艺Ｃ／Ｖ界面结合强，销钉双向切强度高，达到５７．８６ＭＰａ。

| Abstract: | The 4D braiding preforms are densified by either CVI alone or CVI plusing HIP-graphitizationmixing process to make C/C pins. Their double side shear strength is tested and the microstructure isobserved by SEM. It is found that the higher the fiber volume fraction of the preform is, thc higher theshear strength of C/C pins is' The microstructure investigation shows that thc interface bondingstrength of the C/C pin by mixing process (double side shear strength=57. 86MPa) is higher than thatby CVI process alone. |
