The carbon fiber composite material for the new energy automobile body floor and the battery pack cover plate is formed by carbon fiber composite foaming high flame retardance, has a sandwich structure, and can achieve multiple effects of overall heat preservation, heat insulation and weight reduction of a battery pack. Specifically, the composite material can replace a metal vehicle body structure floor to realize the functions of light weight and high strength, has an overall heat preservation and heat insulation function on a battery pack, and also can reduce the weight of a battery pack cover plate, so that the production process can be greatly reduced.

    本发明提供了一种用于新能源汽车车身地板和电池包盖板的碳纤维复合材料,其采用碳纤维复合发泡高阻燃成型,具有三明治结构,能够实现对电池包的整体保温隔热和减重的多重效果。具体的,该复合材料能够替代金属车身结构地板实现轻量化高强度的功能,并且对电池包具有整体保温隔热功能,又同时对电池包盖板减重,可以大幅度减少生产工艺制程。
