摘　　要：用蜃景效应法测试了几种复合材料在不同方向上的热扩散率．发现碳（石墨）纤维单向排布增强铝基复合材料在ｘｙ排布面内各个方向的热扩散率相差很大，而碳（石墨）纤维正交对称排布增强铝基复合材料在ｘｙ排布面内热扩散率差别不大．For various aluminum matrix composites reinforced by unidirectional (uni) or orthogonal (0/90) arrangement carbon fiber, the thermal diffusivities of these samples along different directions are measured by Mirage effect method. From the experimental results, it was found the thermal diffusivities of C/Al with uniarrangement are anisotropic, but with (0/90) arrangement in x_y plane the thermal diffusivities of C/Al are almost the same in different directions. These phenomena were analyzed.
