Abstract: A process for the production of fiber composite hollow SMC components is provided. In the process an SMC-suitable semi-finished fiber composite material is arranged over or around a wash-removable salt core system. The semi-finished fiber composite material and core system are arranged in an SMC mold, followed by molding of an SMC component incorporating the semi-finished fiber composite material and core system. The wash-removable salt may then be removed by washing to result in an SMC component containing a hollow region.

Abstract: An outer skin component for a motor vehicle is designed as a shell component with an outer shell and an inner shell, which are in each case designed as fiber-reinforced plastics shells with a fiber reinforcement embedded into a thermosetting plastic matrix. The fiber reinforcement of the outer shell consists of one or more layers of nonwoven material.

Abstract: A structural component for a motor vehicle is provided. The structural component includes a closed hollow profile including fiber composite material, with a profile outer casing surrounding a profile volume. The structural component also includes at least one reinforcing bulkhead which is arranged in the profile volume on at least one section of an inner casing surface of the profile outer casing. The height of the at least one reinforcing bulkhead, perpendicularly from the inner casing surface, in at least one position in which the at least one reinforcing bulkhead is arranged on the inner casing surface, is lower than a passage height of the profile volume in this position.

Abstract: A method is provided for producing a fiber preform for a composite fiber component. In the method, at least one first fiber structure is braided in a braiding process over the entire length of the fiber preform to be produced and at least one second fiber structure is wound in a winding process over part of the length of the fiber preform to be produced.
