Abstract：With the increase of applications of composites in airplane structures, the thermally-induced stresses are critical issues in composite-metal hybrid structures. In order to analyze thermally-induced structural stresses, accurate structural temperature field value is necessary, while the heat transfer performance of the materials is of great importance for the structural temperature field analysis. Due to the anisotropy of heat transfer performance of composites, which is dependent on the layer and structure of laminates, it results in difficulties in evaluation of thermal conductivities. Based on the ASTM E1461, the samples with different structures were designed, and the thermal conductivities in depth direction and in-plane direction of the T800 carbon fiber reinforced resin laminates were tested through flash method. The thermal conductivities for laminates in different stack types were studied. And also, the thermal stack theory of thermal conductivity for composite laminates in in-plane direction was verified. This work provided a fast approach for evaluation of thermal conductivity of carbon fiber reinforced resin matrix laminated composites.
