摘要: 研究了四种C/C复合材料的磁电阻与测试位向的关系。其中每种试样具有不同结构的预制体，并经过2400℃-2800℃热处理。实验结果表明，这四种材料的磁电阻测试位向曲线形状完全不同，而同一材料的曲线形状基本相同，并且与热处理测试温度和磁场强度无关。经傅里叶函数分析，材料的磁电阻测试位向曲线形状与其预制体纤维的方向有关。Abstract: The magnetoresistance(MR)orientation angle (φ) relationship of four C/C composites, each with a different texture and graphitized at heat treatment temperature (HTT) between 2400 and 2800℃,were investigated. The shape of the MR-φ curve varied with the texture of the C/C composite materials. However, this shape is not affected by HTT, test temperature and the magnetic field intensity. Fourier analysis was applied to each MR-φ curve, indicating that the shape of the MR-φ curve is related to the direction of the fibers in the C/C composites.
