通过宏观力学实验研究了4D轴编C／C复合材料的各向拉伸、压缩和剪切性能。采用ARAMIS非接触式应变测试系统有效地解决了常规测试中应变片和试样变形不协调的问题。结果表明：4D轴编C／C复合材料在拉伸、压缩和剪切时表现出较强的各向异性，具有双模量和非线性特征，径向拉伸表现为裂纹分层扩展，轴向拉伸表现为炭棒拔出，压缩时延性增加，表现为剪切破坏。拉伸时体现出脆性特征，压缩时更多地体现出伪塑性特征；剪切时xz面试样表现为分层破坏，xy面表现为纤维束拔出破坏。
The tensile, compressive and shear property of 4D in-plain C/C composites in each direction were studied by macroscopic mechanical experiment. ARAMIS incontact strain test system was successfully used to solve the incompatible problems produced in using strain gauge to test the properties. The results show that the properties of the 4D in-plain C/C composites exhibit anisotropy, double modules and the nonlinear characteristics. Under tensile load, the specimens show crack delamination growth along the radical direction, and show carbon rod pulled out along the axial direction. Under compress load, the specimens show shear failure caused by the increment of ductility. It embodies brittle in tensile and pseudoplastic in compress. The specimens show delamination failure in xz plane under shear load, and fiber bundle pulled out in xy plane.
