ABSTRACT:
In order to achieve in a sandwich structural part 26 having a honeycomb-shaped support core 20 curved in tension-free condition, which is composed of individually hardened bonded-fiber profile pieces 10, a uniform form stability and a large surface preciseness over a wide temperature range, the individual bonded-fiber profile pieces are constructed tapering in a longitudinal direction of the profile and are octagonal in cross section and the profile walls 16.1, 16.2 of each profile piece are positioned substantially perpendicularly with respect to the local tangential plane T of the curved support-core surface and are exposed alternately peripherally of the profile and, with the mutually facing surfaces, are intended as a defined adhesion surface for a bonding agent 22 for effecting a coupling to an adjacent profile piece.
