Fiber-metal hybrid composite laminate and preparation method thereof

Abstract

The invention discloses a fiber-metal hybrid composite laminate. The fiber-metal hybrid composite laminate comprises a metal base layer, a resin-based composite material layer and an adhesive layer located between the metal base layer and the resin-based composite material layer, wherein the adhesive layer is mainly composed of M layers of adhesive layer base materials and N layers of adhesive films, M and N are integers, N is larger than or equal to 1, N is larger than M, and M is larger than or equal to 0; the fiber-metal hybrid composite laminate can be used in the field of automobile materials, can be co-cured and formed in the compression molding process, and is high in production efficiency; the thickness of the adhesive layer of the fiber-metal hybrid laminate can be controlled by controlling the number of layers of added fiber gridding cloth and the adhesive film, so that the performance of the fiber-metal hybrid composite material is optimized.

Description

technical field [0001] The invention belongs to the field of composite material structural parts production, and more specifically relates to a fiber-metal hybrid composite laminate and a preparation method thereof. Background technique [0002] Hybrid composite materials combine the characteristics of traditional fiber composite materials and metal materials. They have high specific stiffness and specific strength, excellent fatigue performance and high damage tolerance. Compared with metal materials, they can achieve significant weight reduction effects. An important development direction of lightweight automobile structure. [0003] The application of hybrid composites in automobiles has different requirements than in aircraft. One of the main aspects is the manufacturing cost. The manufacturing cost of automotive structural parts is much lower than that of aircraft. Therefore, the structure of fiber-metal hybrid composites for automobiles is relatively simple, including...

AI Technical Summary

Problems solved by technology

[0004] Since prepreg molding must have a certain pressure, the adhesive layer is extruded during the curing process, and the current co-curing molding technology has the problem that the thickness of the adhesive layer cannot be controlled

However, the thickness of the adhesive layer has an important influence on the interfacial bonding strength between metal and resin matrix composites, which in turn affects the performance of fiber-metal hybrid composites.
