Title:
PLATE-LIKE BODY
Document Type and Number:
WIPO Patent Application WO/2010/007683
Kind Code:
A1
Abstract:
This invention provides a plate-like body which can ensure satisfactory rigidity without increasing plate thickness. A number of convexes (2) are formed in an aluminum flat plate by embossing in an aligned state so that the flat plate part does not remain linearly between the convexes (2). The convexes (2) have a regular hexagonal shape as viewed planarly, and the longitudinal section, which passes through an apex which makes an opposing corner, is circular. The optimal value of convex height (H)/convex width (W1) is a value in an experiment example, i.e., about 16.3% which is a value just before the start of blunting of the percentage performance improvement. From the viewpoint of a satisfactory percentage performance improvement, however, the convex height (H)/convex width (W1) value is suitably not less than 12% and not more than 20.0%.
