Abstract
A sandwich structure has a core which comprises an array of core units (,) that are arranged in a staggered pattern between the walls (,) of the structure such that in a first direction (II—II) adjacent core units (,) are substantially aligned whereas in another direction (III—III) at least some adjacent core units (,) partly face each other and the core units (,) are arranged in said first direction (II—II) at generally larger mutual spacings (,) 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 (,) form no through-gaps in the core webs so that the risk of crack formation in the walls (,) and between walls and core is minimized.
