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.

Embodiment

[0024] Such as figure 1 As shown, the fiber-metal hybrid composite laminate includes a layer of 1.5mm thick steel plate, a layer of carbon fiber composite material with a thickness of about 1.5mm, and an intermediate glue layer, and a certain number of layers of Nylon fiber mesh cloth is used as the base material of the adhesive layer. The laying sequence is steel plate-adhesive film-adhesive base material-adhesive film-adhesive base material-adhesive film-carbon fiber prepreg, and the adhesive layer base material and adhesive film are laid alternately to realize the control of the thickness of the adhesive layer. After the layer is laid, put it into the mold, and use the molding process to co-cure the adhesive film and the prepreg to obtain a carbon fiber-steel hybrid composite laminate with a certain thickness of the adhesive layer. Concrete preparation method is as follows:

[0025] a) Perform solvent scrubbing, degreasing, sandblasting and silanization on the surface of ...

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...
