Abstract: The present invention relates to processes for producing sandwich elements, where the sandwich elements comprise a rigid polyurethane foam as core foam surrounded entirely or to some extent by a plastics resin comprising reinforcing-agent layers, by producing the rigid polyurethane foam on the reinforcing-agent layers and then saturating the reinforcing-agent layers in a liquid resin and hardening the resin. The present invention further relates to sandwich elements that can be produced by a process of the invention, and also to the use of these sandwich elements as wind-turbine blade, aircraft wing, wind-turbine nacelle, boat-hull, or housing for vehicles.
