Carbon fiber and metal connecting structure and manufacturing method thereof for electric vehicles

Abstract

The invention discloses a carbon fiber and metal connecting structure and a manufacturing method thereof for electric vehicles. The carbon fiber and metal connecting structure comprises a carbon fiber floor and metal stiffening beams; carbon fiber connecting grooves are formed in the carbon fiber floor; the metal stiffening beams are inserted into the carbon fiber connecting grooves and bonded to the carbon fiber connecting grooves through binding agents. The manufacturing method for the carbon fiber and metal connecting structure for the electric vehicles includes the following step that (1) the carbon fiber floor with the carbon fiber connecting grooves is prepared; (2) the inner surfaces of the connecting grooves are pre-treated and coated with the binding agents; and (3) the metal stiffening beams are inserted into the connecting grooves and the binding agents are cured. Carbon fiber materials and metal materials are tightly combined through the carbon fiber connecting grooves, so that the number of fasteners and parts is greatly reduced, and the assembly time and cost are remarkably reduced. Besides, the connecting strength and connecting durability are improved while advantageous features such as high strength, small mass, corrosion resistance and fatigue resistance of carbon fibers are achieved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber automobile composite material parts connection, in particular to a carbon fiber and metal connection structure for an electric vehicle and a manufacturing method thereof. Background technique [0002] Light weight, high strength, and good durability carbon fiber composite materials are new materials that have been receiving much attention in the process of automobile lightweight. Wide application has become possible. At present, the use of carbon fiber composite materials in the field of electric vehicles is one of the important means to solve the problem of overweight batteries and short cruising range. The use of carbon fiber composite parts can not only reduce the weight of the body and increase the cruising range, but also use the designability of carbon fiber composite materials to flexibly change the structure of the car to achieve a personalized design that is more in line with people...

AI Technical Summary

Problems solved by technology

[0003] A problem brought about by the application of carbon fiber auto parts is that most of the metal parts were connected by welding before. After the use of carbon fiber composite materials, the traditional connection method between metal parts can no longer meet the needs of objective applications. Therefore, New connection designs must be proposed to meet the connection needs between carbon fiber composites and other metal materials
