Abstract

The invention discloses a connection method for a carbon fiber composite material and an aluminum alloy plate. The connection method comprises the following steps of: sequentially and closely overlapping the carbon fiber composite material, a titanium foil, a red copper plate and the aluminum alloy plate from bottom to top to form a to-be-welded region; welding the to-be-welded region by adoptingelectron beams; and carrying out temperature-maintaining cooling thermal treatment after welding is ended. The method can solve the problem that the carbon and aluminum elements are not wet and realizes metallurgical connection of the carbon fiber composite material and the aluminum alloy plate.

Description

technical field [0001] The invention relates to a connection method of a carbon fiber composite material and a metal plate, in particular to a connection method of a carbon fiber composite material and an aluminum alloy plate. Background technique [0002] Carbon fiber composites are composite materials with carbon elements as the matrix and particles or fibers as the reinforcing phase. Carbon fiber composite materials have low density, high specific strength and specific modulus, stable structural dimensions, and excellent properties such as high temperature resistance, fatigue resistance and wear resistance. They are widely used in industries such as national defense, aerospace, aviation, automobiles, and instrumentation. field. [0003] In order to realize the lightweight of the car and ensure the driving safety and performance of the car, it can be considered to combine carbon fiber composite materials and aluminum alloy plates for mixed use. However, carbon fiber comp...
