Structure, molded article, and method for manufacturing same

Abstract

A structure 1 is provided with a core layer 2 where a plurality of polygonal-cylindrical or circular-cylindrical cells S are disposed adjoiningly inside and skin layers 3, 4 that are provided on the upper and lower surfaces of the core layer 2 . Communication portions 6 for communicating with adjacent cells S are formed in the core layer 2 . A molded article is formed by providing a bent portion to the structure 1.

1 . A molded article comprising a structure, wherein a bent portion is formed through a bending process in the structure, the structure including:
 a core layer that is formed by folding a sheet material molded of a single plastic sheet into a predetermined shape so that the core layer is sectioned into a plurality of cells that are formed by the polygonal-cylindrical or circular-cylindrical sidewalls and are disposed adjoiningly inside; and   skin layers provided on the upper and lower surfaces of the core layer,   wherein, in the core layer of the structure, one end surface of each cell is closed by an upper or lower wall having a two-layer structure and the other end surface is closed by a lower or upper wall having a one-layer structure, and an opening is formed in the upper or lower wall closing one end of the cell.   
     
     
         2 . The molded article according to  claim 1  wherein communication portions for connecting adjacent cells to each other are formed in the core layer of the structure.
