Document Type and Number:
Japanese Patent JPH11509145
Kind Code:
A
Abstract:
A sandwich structure has a core which comprises an array of core units (3) that are arranged in a staggered pattern between the walls (1,2) of the structure such that in a first direction (II-II) adjacent core units (3) are substantially aligned whereas in another direction (III-III) at least some adjacent core units (3) partly face each other and the core units (3) are arranged in said first direction (II-II) at generally larger mutual spacings (7) than in said second direction (III-III). The thus formed core is drapeable yet structural, so that it can conform to curved structures and the staggered mutual spacings (7) form no through-gaps in the core webs so that the risk of crack formation in the walls (1,2) and between walls and core is minimized.
