Abstract: The present invention relates to a formwork system (1) comprising a form lining (2) and at least one shaped element (10) which is attached to the rear side (4) of the form lining (2). The form lining (2) and the shaped element (10) have been produced by a 3D printing method. This is preferably carried out in a common 3D printing process, but the form lining (2) and the shaped element (10) can also be produced in separate 3D printing processes, with the shaped element (10) then being attached to the rear side (4) of the form lining (2).

Abstract: The invention relates to a method for designing the wall thickness of components that are permanently subjected to static and/or dynamic loading, the components being made of a fiber reinforced polymer material. In a first step, the orientation of the fibers in the fiber reinforced plastic and the position of the weld lines in the component are determined by a first simulation calculation. A degree of utilization of the strength of the component is calculated by a second simulation calculation. The wall thickness of the component is adapted to the result of the second simulation calculation, and the previous steps are repeated if a change of the wall thickness has been carried out. The invention also relates to a component of a fiber reinforced polymer material that has a wall thickness designed by the method according to the invention.
