Preparation method of composite material with high thermal conductivity structure

The invention relates to the technical field of high-thermal-conductivity resin-based composite materials, in particular to a preparation method of a high-thermal-conductivity structural composite material. The method comprises the following steps: alternately laying a resin film and high-thermal-conductivity fibers, compacting, and compounding to obtain a preform; the prefabricated body is cut in the direction perpendicular to the Z direction, and a resin film with Z-direction fibers is obtained; and infiltrating a resin film with Z-direction fibers into the fiber laying layer by adopting an RFI process to obtain the high-thermal-conductivity composite material. The preparation method of the composite material with the high-thermal-conductivity structure aims to solve the problem that the thermal conductivity of the composite material in the thickness direction is difficult to improve. 本发明涉及高导热树脂基复合材料技术领域，具体涉及一种高导热结构复合材料的制备方法。该方法包括步骤：将树脂膜与高导热纤维交替铺放后压实，复合得到预制体；将预制体沿垂直于Z向的方向切割，得到带有Z向纤维的树脂膜；采用RFI工艺将带有Z向纤维的树脂膜渗入
