Title:
SANDWICHED ALUMINUM PANEL
Document Type and Number:
Japanese Patent JP2543649
Kind Code:
B2
Abstract:
PURPOSE: To improve the bending property and shock absorbability of a panel and also to raise productivity by composing a sandwich panel taking a network- like formed body as a core of integrally extruded materials.
CONSTITUTION: An aluminum extruded material 18 having lateral plate parts 22 between belt-like longitudinal plate parts 20 of a prescribed width is made. Plural blanked open holes 24 are mutually zigzag formed on the lateral plate parts 22 having a shape that H-shapes are superimposed. When this is extended in the breadthwise direction while allowing expansion deformation in the longitudinal direction, parts where are not restrained with connecting parts 26 are bending or curving deformed, the open holes 24 are approximately hexagonally expanded and made into the network-like formed body 12 as a whole. By superposing brazing sheets 14, 16 of which the insides are cladded with a brazing filler metal on both sides of this network-like formed body 12 and brazing the end faces of each longitudinal wall part 20, the integral aluminum sandwich panel 10 is manufactured.
