Abstract

The invention discloses a preparation method of a carbon fiber reinforced polyimide fiber metal laminate, belonging to the technical field of composite materials. The preparation method of the carbon fiber reinforced polyimide fiber metal laminate comprises the following steps: cutting a metal plate and a carbon fiber reinforced polyimide prepreg to reach required sizes; cleaning the metal plate; performing anode oxidation on the metal plate; painting a primer on the surface of the processed metal plate and alternatively spreading and placing the metal plate coated with the primer and the prepreg in a mould, warming and pressurizing the spread metal plate and prepreg for being cured; and after curing is ended, naturally cooling to obtain the carbon fiber reinforced polyimide fiber metal laminate. The carbon fiber reinforced polyimide fiber metal laminate prepared by adopting the preparation method has excellent characteristics of high temperature resistance and fatigue resistance, has the advantages of corrosion resistance, inflame retardance, impact resistance and the like, and can be widely applied to the aerospace field; the cost of the carbon fiber reinforced polyimide fiber metal laminate is far lower than that of a carbon fiber reinforced composite material.

Description

technical field [0001] The invention relates to a method for preparing a fiber metal laminate, in particular to a method for preparing a carbon fiber reinforced polyimide matrix fiber metal laminate, and belongs to the technical field of composite materials. Background technique [0002] Fiber-Metal Laminates (FMLs for short) is an interlayer hybrid composite material system formed under a certain temperature and pressure after alternate laying of metal sheet layers and fiber composite material layers. FMLs combines the characteristics of traditional fiber composite materials and metal materials, and makes up for the shortcomings of single composite materials and metal materials. It not only has high specific stiffness and specific strength, but also has the toughness and machinability of metal materials. and damage tolerance properties, making it an ideal choice for aircraft structures. [0003] FMLs are formed by laying alternate layers of metal sheets and fiber composite...
