Description

technical field [0001] The invention discloses a carbon fiber composite material applied to new energy vehicles and a preparation method thereof, specifically in the technical field of new energy vehicles. Background technique [0002] All kinds of materials, including metals and non-metals, have been continuously developed. The requirements for materials are always developing in the direction of light weight, multiple functions, high strength and low price. With the development of new energy vehicles, the requirements for technological materials have reached very urgent needs. Since new energy vehicles use batteries as power, if the weight of new energy vehicles is heavy, it will greatly affect the endurance of new energy vehicles. Although the existing carbon fiber materials have high strength, their quality does not reach the level of new energy vehicles. assembly requirements. To this end, we propose a carbon fiber composite material for new energy vehicles and its pre...
