Abstract: A method of manufacturing a core for a production process and to a core manufactured in accordance with the method are provided. The method includes providing a mold containing a soluble substance and one or more fibers and causing the soluble substance to solidify around the one or more fibers.

Abstract: A method for producing a component from a fiber composite. A number of layers of a dry fibrous material are stacked to form a pile, the pile is covered by a thermoplastic film in a gas-tight manner, the inner space occupied by the pile within the film is pumped dry and the layers are fixed to form a preform that is stable during transport, the preform is reshaped, a liquid thermosetting material is inserted into the inner space by infiltration of the fibrous material, and the preform is hardened with the infiltrated fibrous material to form the finished component, the film binding permanently as the surface. The invention also relates to a component produced in such a way, and to a corresponding preform. The production method provides a process-integrated surface finishing of the fiber composite. The surface properties are created by the bound thermoplastic film.

Abstract: A mandrel for manufacturing a three-dimensional structure from a composite material. The external surface of the mandrel can at least partially correspond to the inner surface of the three-dimensional structure. The mandrel can include a plurality of expandable particles configured to increase responsive to a threshold condition. The mandrel can be configured to crack responsive to a triggering condition.

Abstract: A process for the production of a component (1) made of a fiber composite material, and also a component (1) produced in this way, are stated, where a foil composite (7) with a thermoplastic outer foil (6) and with a thermoplastic inner foil (5) is produced, where the modulus of elasticity (E) of the inner foil (5) within a temperature range is smaller than the modulus of elasticity (E) of the outer foil (6), the inner foil (5) of the foil composite (7) is bonded to a molding (4) comprising a fiber material (2) and comprising a thermoset (3), the molding (4) is hardened, and the foil composite (7) is subjected to a heat treatment in the temperature range within which the modulus of elasticity (E) of the inner foil (5) is smaller than the modulus of elasticity (E) of the outer foil (6), where the outer foil (6) undergoes stress relaxation.
