Abstract: In this paper, the thermal conductivity behavior of biaxial warp knitted fabric reinforced resin foam sandwich composite was studied by finite element method and experimental method respectively, and the effects of fabric structure, boundary conditions and material properties on the thermal conductivity of the composite were analyzed. The heat conduction behavior of sandwich composite was analyzed by finite element method. It was found that the difference of thermal conductivity of each component and the direction of temperature gradient both affected the thermal conductivity behavior of sandwich composite, and the latter effect was more obvious. The heat conduction pro-cess, temperature distribution and final heat equilibrium temperature of sandwich composite were measured by infrared thermal imaging test, and the results are consistent with those obtained by finite element method.

Key words: sandwich composite, finite element method, heat conduction, thermal conductivity
