Abstract: An induction heated tool system for receiving and heating polymer-fiber components from a starting temperature to a target temperature includes a tool part having a receiving cutout, the tool part formed from a thermally dimensionally stable material so it has a coefficient of thermal longitudinal expansion less than 10×10−6 K−1, or less than 5×10−6 K−1, or less than 4×10−6 K−1 in the plane of the largest dimension of the receiving cutout, at temperatures between the starting and target temperatures. A receiving cutout for receiving a polymer-fiber component is in the tool part, the receiving cutout delimited by a receiving surface portion so a polymer-fiber component received in the receiving cutout can lie against the receiving surface portion. A susceptor element includes a ferromagnetic material with a first Curie temperature. The susceptor element is on a surface portion of the tool part outside the receiving cutout and the receiving surface portion.

Abstract: A mold core for producing a component of fiber composite material with a cavity makes a particularly simple and efficient demolding process possible by the mold core extending along a longitudinal axis and in the form of a hybrid core and which includes, viewed in a cross section perpendicular to the longitudinal axis, a first core portion and a second core portion, wherein the first core portion has a thickness that is substantially greater than a thickness of the second core portion. The first core portion is formed from a first material with high stiffness and low coefficient of thermal expansion, and the second core portion is formed from a second material that differs from the first material, and is configured such that, under predetermined conditions, its form changes in a predetermined manner such that removal of the mold core from a cavity in the cured component is made easier.

Abstract: A method for the additive manufacture of a component within a receiving unit using a powdery material wherein, in one step, the powdery material is introduced into the receiving unit via a feed unit. In a further step, an oscillation is applied to the powdery material introduced into the receiving unit. In a further step, the oscillation is applied over a period of time to the powdery material introduced into the receiving unit until a predetermined distribution of the powdery material within the receiving unit is achieved. In a further step, at least a part of the powdery material within the receiving unit is solidified after the predetermined distribution of the powdery material has been achieved. An apparatus for the additive manufacture of a component within a receiving unit using a powdery material is also described.

Abstract: Method for producing composite components having an undevelopable surface. To be able to maintain the tolerances when manufacturing especially large components in the case of composite components with undevelopable surfaces, it is proposed according to the invention to drape a cut-to-size blank on a molding tool and to determine the deviation of the cut-to-size blank edge from the setpoint cut-to-size edge. Then, on the basis of the deviation, a new cut-to-size blank edge is calculated, and a new cut-to-size blank is created and re-draped for examination purposes. The method is repeated until the deviations are below a tolerable threshold value. The method is furthermore carried out for each textile ply of the composite component.

Abstract: An apparatus for carrying a fiber composite resin system in a heat transfer device, in particular an autoclave, for transferring heat between the fiber composite resin system and a directed gas flow, to produce a fiber composite aircraft component. The apparatus comprises a carrier structure for carrying the fiber composite resin system, the carrier structure having at least one flow path which, when the apparatus is accommodated in the heat transfer device, extends from an inlet on a side facing the directed gas flow along the fiber composite resin system accommodated by the carrier structure, to allow heat exchange between the gas flow in the flow path and the fiber composite resin system, and a diverting device for diverting at least a part of the directed gas flow when the apparatus is accommodated in the heat transfer device, to feed this part to the carrier structure flow path.

Abstract: A conveying installation by way of which the 3D printing rate can be increased and the reliability of transporting a semi-finished product to be processed in an additive manufacturing machine can be improved. The conveying installation comprises a longitudinal conveying mechanism which conveys the semi-finished product along a conveying direction in that a preferably continuously revolving conveying arrangement, for example a conveyor belt or a conveying belt, engages the semi-finished product in a force-fitting and/or form-fitting manner

Abstract: A component made of a fiber-reinforced plastic, having a first surface portion, a second surface portion and a transition portion, which is enclosed by the first surface portion and the second surface portion, wherein surface tangents to the first surface portion and the second surface portion are not parallel, at least in regions adjacent to the transition portion. The transition portion has a curvature adjoining the adjacent surface portions in a tangentially constant manner, wherein an arrangement of at least two layers made of a fiber-reinforced plastic extends from the first surface portion, over the transition portion, onto the second surface portion, and fibers at least of one of the layers run with an unchanging orientation on the first surface portion and the second surface portion and, on the transition portion, run in a laterally offset, inflected or curved manner along the running direction.
