CELLULAR FILLER FOR FLAT AND CURVE MULTILAYER PANELS Russian patent published in 1996 - IPC

Abstract RU 2069625 C1

FIELD: multilayer structures in mechanical engineering field. SUBSTANCE: cellular filler has pyramidal form hollow protrusions with truncated vertexes. Truncated vertexes in adjacent rows are directed in opposite sides in respect to plane passing through their bases. Side ribs of protrusions are shorn with formation of diamond-shaped holes. Bases of truncated vertexes have holes for joining outer layers of panel. EFFECT: improved quality of cellular filler. 4 dwg
