采用预浸炭布铺层制作炭／酚醛树脂基层合板，后经炭化、致密制备了二维炭／炭复合材料（２Ｄ－Ｃ／Ｃ）．检测了其工艺过程中的尺寸变化，测试了力学、导热、热膨胀、等离子烧蚀性能。结果表明，２Ｄ－Ｃ／Ｃ在工艺过程中Ｚ向有明显的收缩现象，炭化收缩率达６．９９％，石墨化收缩率达５．５５％。２Ｄ－Ｃ／Ｃ的层间剪切强度（ＩＬＳＳ）大于１２．６ＭＰａ，拉伸强度大于１３３．７ＭＰａ，拉伸模量大于５８．６ＧＰａ，压缩强度平均为２２８ＭＰａ。石墨化２Ｄ－Ｃ／Ｃ的导热系数随温度的升高而下降，而未石墨化随温度的升高而增加。２Ｄ－Ｃ／Ｃ的导热、热膨胀、等离子烧蚀性能都具有明显的各向异性，Ｚ向和Ｘ－Ｙ面内相差较大。
A carbon / phenolic resin-based laminate was prepared by pre-impregnated carbon cloth, and then a two-dimensional carbon / carbon composite (2D-C / C) was prepared by carbonization and compacting. The dimensional changes in the process were tested and the mechanical, thermal, thermal expansion and plasma ablation performances were tested. The results show that 2D-C / C shrinks markedly in the Z direction during the process, with a carbonization rate of 6.99% and a graphitization rate of 5.55%. The interlaminar shear strength (ILSS) of 2D-C / C is greater than 12.6 MPa, the tensile strength is greater than 133.7 MPa, the tensile modulus is greater than 58.6 GPa, and the compressive strength is 228 MPa. The thermal conductivity of graphitized 2D-C / C decreases with increasing temperature, while the non-graphitization increases with increasing temperature. 2D-C / C thermal conductivity, thermal expansion, plasma ablation properties have obvious anisotropy, Z-and X-Y plane within a larger difference.
