Carbon fiber reinforced aluminum alloy layer pipe component forming process and forming mold

Abstract

The invention discloses a carbon fiber reinforced aluminum alloy layer pipe component forming process and a forming mold. A process route of 'heat treatment of aluminum alloy inner and outer pipe blanks, forming of an aluminum alloy outer pipe blank soft mold, layered laying of carbon fiber prepreg and outer layer aluminum alloy pipe forming parts, composite pressing of carbon fiber reinforced aluminum alloy layer pipe pre-forming parts, and mold unloading' is provided for fiber metal layer pipe component forming; a delicate composite forming process can be developed according to plastic performances and metallurgical bonding performances of different series of aluminum alloys; a layer pipe component composite forming integrated preparation scheme is realized; the process is particularly suitable for preparing fiber metal layer pipe components with special-shaped sections; the forming problem is solved when parts are compounded; the problem of secondary machining difficulty of fiber metal layer pipes is solved; the application range of fiber metal composite materials is widened; and references are provided for forming of fiber metal layer pipe composite materials in complex shapes.

Description

technical field [0001] The invention belongs to the technical field of tube component forming, and relates to a carbon fiber reinforced aluminum alloy layer tube component forming technology, in particular to a carbon fiber reinforced aluminum alloy layer tube component forming process and a forming die. Background technique [0002] (1) Explanation of terms: [0003] Fiber metal laminates (FMLs for short): It is a sandwich material formed by sequentially laying metal sheets, fiber materials and connecting agents, and curing under specific temperature and pressure conditions. [0004] Layer tube component: a type of thin-walled part that is prepared from a tube as the original blank by stamping. [0005] Carbon fiber prepreg: a material formed by compounding epoxy resin on carbon fiber through high temperature and high pressure technology. [0006] Compression molding: A process in which a certain amount of prepreg is put into the mold cavity at the molding temperature, an...
