Abstract: A method of manufacturing an arc-shaped fiber composite component includes forming a preform with a planar fiber layer arrangement formed along an arc and having an outer edge assigned to a convex outer side of the arc. The outer edge is formed with gaps extending into the arrangement in such a manner that a contour of the gaps is formed at least in sections near a target contour of a respective recess to be provided in the component. The preform is formed such that a first region of the arrangement, adjacent to the outer edge and extending substantially in the direction of the arc, is bent or angled relative to a second region of the arrangement, adjacent to the first region remote from the outer side of the arc. The gaps that the preform has prior to reshaping merge into recesses of the formed preform and remain open.

Abstract: A method for treating a surface of a fibre composite component, wherein an abrasive removal of the surface of the fibre composite component takes place by blasting a removing agent transported by a gaseous transporting fluid onto the surface of the fibre composite component by a feed nozzle and a suction extraction of the removing agent and material removed by the removing agent takes place by an extraction nozzle arranged in the region of the feed nozzle.

Abstract: A shaping device for producing a profiled component includes a lay-on unit, a press-on unit and a pressure application unit. The lay-on unit has a support surface for laying on a semi-finished product to be shaped. The press-on unit presses a semi-finished product to be shaped onto the support surface. The pressure application unit has, at least on the side that faces the semi-finished product, a bendable shell for lying on the semi-finished product in an unshaped first state and for lying thereon in a shaped second state, as well as a pressure-transmitting and deformable filling. The pressure application unit can be arranged between the press-on unit and a semi-finished product to be shaped. The press-on unit has a bendable surface lying on the pressure application unit, which bendable surface transmits the force for the shaping onto the pressure application unit. The semi-finished product to be shaped may be a fibre-reinforced composite material.

Abstract: A process for producing a hollow profiled component formed by joining at least two laminated component elements, includes the steps of laminating a first of the component elements with at least one indentation, arranging a preformed hollow body in the indentation, applying an adhesive agent to a surface area of the first component element next to the indentation, placing the first component element together with the hollow body on the second component element with the indentation facing the second component element and the surface area provided with the adhesive agent contacting the second component element, covering the two component elements with a non-rigid fluid-tight covering, the interior of the hollow body being sealed off from the interior of the covering and being fluidically connected with the ambient exterior environment, placing the covered component elements in a pressure chamber, and applying a vacuum to the interior of the covering.

Abstract: A method of producing a reinforced plastic profile (10) with a uniform profile cross section, in which the transverse reinforcement (12) is formed by a linked, knitted, sewn or woven tube. Such a tube can be seamlessly formed continuously during the production of the plastic profile (10), which is preferably performed by pultrusion.

Abstract: The invention is a profiled bar, in particular sprung bars, in which a reinforcement of both synthetic fibers and natural fibers is embedded in a plastic matrix. The proportion of synthetic fibers can be reduced by using natural fibers derived from regrowing raw materials. This improves environmental compatibility and makes it easier to dispose of such sprung bars. The sprung bars are used in particular to form bottom sprung supports for furniture for sitting and lying on, and in particular for slatted frames.
