摘　　要：采用液相浸渍工艺和化学气相沉积工艺制备了不同炭基体结构的2D-炭／炭复合材料。通过纳米压痕法研究了树脂炭基体及热解炭基体的压痕模量和压痕硬度。结果表明，树脂炭基体的压痕模量为25．3GPa，压痕硬度为3．7GPa；热解炭基体的轴向压痕模量为24．5GPa，压痕硬度为2．4GPa。2-D carbon/carbon composites with different carbon matrices were prepared by liquid impregnation process and chemical vapor deposition process, respectively. Nanoindentation modulus and nanoindentation hardness of resin carbon matrix and pyrolytic carbon matrix were researched by nanoindentation technology. As a result, nanoindentation modulus and nanoindenta- tion hardness of resin carbon matrix are 25.3GPa and 3.7GPa, respectively. Nanoindentation hardness and axial nanoindentation modulus of pyrolytic carbon matrix are 24.SGPa and 2.4GPa, respectively.
