The invention provides a lightning protection composite material and a preparation method thereof. The preparation method of the lightning protection composite material comprises the following steps:preparing a carbon fiber/phenolic resin prepreg, wherein the carbon fiber/phenolic resin prepreg is a material formed by impregnating a carbon fiber fabric into phenolic resin; laying the carbon fiber/phenolic resin prepreg on a prefabricated part plate of a carbon fiber reinforced epoxy resin matrix composite material; and carrying out vacuum hot pressing on the laid material to prepare the lightning protection composite material. According to the invention, the carbon fiber/phenolic resin prepreg and the matrix material carbon fiber reinforced epoxy resin matrix composite material are compounded through vacuum hot pressing so that the prepared lightning protection composite material has relatively high conductivity and a relatively good lightning protection effect.
本发明提供了一种雷电防护复合材料及其制备方法。所述雷电防护复合材料的制备方法包括如下步骤:制备碳纤维/酚醛树脂预浸料,所述碳纤维/酚醛树脂预浸料是将碳纤维织物浸渍于酚醛树脂后形成的材料;将所述碳纤维/酚醛树脂预浸料铺设至碳纤维增强环氧树脂基复合材料的预制件板上;对铺设后的材料进行真空热压,制得雷电防护复合材料。本发明将碳纤维/酚醛树脂预浸料与基体材料碳纤维增强环氧树脂基复合材料通过真空热压进行复合,制得的雷电防护复合材料具有较高的电导率以及较优的雷电防护效果。
