Abstract

The invention discloses a forming method of a fiber-reinforced thermoplastic resin aluminum alloy layer board part. The forming method comprises the following steps: (1) placing a fiber-reinforced thermoplastic resin aluminum alloy layer board between a female die and a male die; (2) heating an aluminum alloy layer, and heating an aluminum alloy layer in the fiber-reinforced thermoplastic resin aluminum alloy layer board to a fiber-reinforced thermoplastic resin melting temperature and preserving heat for a certain time; (3) die assembling and pressure maintaining: maintaining a certain pressure after assembling the dies, and lasting for a certain time; and (4) die stripping and cooling. According to the forming method disclosed by the invention, the fiber-reinforced thermoplastic resin is heated and melted by aluminum alloy current with self-resistance, and the formed part is cured under maintained pressure, so that the problem of delamination between the aluminum alloy layer and the fiber thermoplastic resin layer in a forming process is solved; and by softening the fiber-reinforced thermoplastic resin before the fiber-reinforced thermoplastic resin is melted, the deformation capability of the fiber-reinforced thermoplastic resin layer is improved.

Description

technical field [0001] The invention relates to the technical field of forming methods for fiber metal laminates, in particular to a forming method for fiber reinforced thermoplastic resin aluminum alloy laminate parts. Background technique [0002] Fiber metal laminate is a super-hybrid structural material obtained by alternately laminating high-strength aluminum alloy sheets and fiber prepregs and forming them through a certain curing process. Compared with a single aluminum alloy sheet, the fiber metal laminate has light weight, high strength, good electrical conductivity, excellent impact resistance and damage tolerance performance; The optimal design of the structure can be achieved to the greatest extent by considering the ply thickness, the number of plies and the orientation of the fibers. [0003] The performance difference between the layers of fiber metal laminates is large, and the deformation ability of fibers is limited, which makes it difficult to form lamina...
