Zusammenfassung: | The invention provides a fiber metal laminate thermal medium variable energy rate surface force loading forming method, and belongs to the field of composite material forming. The novel method is a novel technology integrating high-energy-rate impact forming and liquid-filling static pressure forming in a crossed mode, and has the advantages of the two. The problems that in traditional forming, fiber materials are stacked and distributed unevenly, and in the material curing process, interlayer residual stress is large, and resilience is large are solved. The part rigidity can be enhanced, the die number is reduced, the equipment tonnage is reduced, and the forming efficiency is improved. The forming process mainly comprises the steps that a mold is cleaned, the surface of a metal layer is treated, a blank layer is placed on the forming mold, the mold is closed downwards, liquid is loaded, heating is conducted till thermoplastic resin enters a viscous state and high-elastic state mixed state, and at the moment |
