炭/炭复合材料的结构对磁电阻一位向曲线形状的影响
Influence of texture of C/C composites on the shape of magnetoresistance-orientation angles curves
摘要
Abstract
The magnetoresistance( MR) -orientation angle (ψ) relationship of four C/C composites, each with a different texture and graphitized at heat treatment temperature (HTT) between 2 400 and 2 800℃, were investigated. The shape of the MR- ψ 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-ψ curve, indicating that the shape of the MR-ψ curve is related to the direction of the fibers in the C/C composites.关键词
