摘要： 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.

摘要： A safety steering column made of wound fiber-reinforced synthetic materials manufactured economically and simply, yet simultaneously with due regard to its deformation characteristics in response to axial compressive overloading under various operating conditions. For this purpose the steering column is wound as a rotationally symmetrical tubular body having five component integral sections (3, 4, 5, 6, and 7). The component sections (3 and 7) are relatively thick-walled connecting tubes to provide a torque input section and a torque output section provided with connectors (8) for steering wheel hub and for a steering mechanism. An intermediate section (5) of the steering column is a cylindrical, relatively thin-walled tube with a larger diameter (d.sub.2) compared to the connecting sections. Conical transition sections (4 and 6) preferably extend between the intermediate section and the connecting tubes or sections. The wall thickness of these transition sections diminishes uniformly from the connecting section in the direction toward the intermediate section for improving the buckling ability. A geodetic winding procedure is preferably applied for winding the columns.
