Carbon fiber reinforcement aluminum alloy mortise and tenon structure and preparation method thereof

Abstract

The invention discloses a carbon fiber reinforcement aluminum alloy mortise and tenon structure which comprises a mortise piece and a tenon piece, wherein the mortise piece is provided with a mortise; a tenon connection part of the tenon piece is inserted into the mortise; at least one inner surface of the mortise is coated with carbon fiber composite cloth; and the tenon connection part is in interference fit with the mortise coated with the carbon fiber composite cloth. The carbon fiber is high in axial strength and module, low in density, high in specific performance, good in fatigue resistance, low in thermal expansion coefficient and good in corrosion resistance, has no creep deformation, has superhigh temperature resistance at the non-oxidizing environment and has anisotropism, and the specific heat and conductivity of the carbon fiber is between the specific heat and conductivity of nonmetal and the specific heat and conductivity of metal. With the utilization of the carbon fiber composite cloth to reinforce the mortise and tenon structure, a tenon pulling phenomenon of the mortise and tenon structure can be retarded effectively. The carbon fiber reinforcement aluminum alloy mortise and tenon structure has the characteristics of high strength and rigidity, reduction in energy consumption ability, and the like, and can be widely applied to the fields of automotive industry, sports equipment, fire protection, and the like.

Description

technical field [0001] The invention relates to a mounting structure for aluminum alloy components in a vehicle frame, especially a carbon fiber reinforced aluminum alloy mortise and tenon structure, and a preparation method for the structure. Background technique [0002] New energy vehicles are the future development direction of my country's automobile industry. In order to reduce the energy consumption of new energy vehicles and increase the mileage, it is necessary to adopt a lightweight body structure. For this reason, the material of the body frame of the existing new energy vehicles is generally aluminum alloy. , the corresponding structure adopts connection methods such as welding, riveting or screw fastening, but the above connection methods will lead to increased defects and reduced strength of the aluminum alloy at the connection part. Referring to the beams and columns of ancient Chinese architecture, the mortise and tenon structure is used as the basic node to c...
