  • Bent structure comprising outer metal sheets in a soft W condition bonded by an adhesive layer
    Patent number: 5185198
    Abstract: To improve forming properties of laminated structures comprising two sheets of a non-ferrous metal alloy connected by an adhesive, which hardens at heating and between which an adhesive layer is bonded to the metal sheets, a new sequence of heat treatments is proposed. The alloy of the sheets is in soft condition before the sheets are bonded to each other. The bonding temperature and time are selected such that it remains substantially in soft condition and only after forming further heating is applied to obtain hardening of the alloy sheets.
