Embodiment Construction
[0025] Now in conjunction with the magnesium alloy honeycomb panel production process schematic diagram, the present invention is further specifically described:
[0026] (1) Manufacture of honeycomb core structure 1: The magnesium alloy, such as AZ31B, is rolled into a foil with a thickness of 0.08-0.25mm by cold rolling or hot rolling. After heat treatment and surface treatment, its performance parameters are shown in Table 1. ; Cut the above foil material into foil strips with a width of 6-38mm, such as figure 1 shown;
[0027] Then the above-mentioned foil strips are accurately and non-damagingly bent to form a honeycomb core blank, such as figure 2 As shown, the formed excessive fillet radius is 0.45mm, corresponding to it, the forming strain rate is 0.0015 / s;
[0028] Place the formed honeycomb core blank on the working platform for gluing, positioning, and lamination, and then cure it at a specified temperature of 80-120°C and a specified pressure of 3-10MPa to make ...
