    Abstract: A material for use in vacuum bagging a component. The material includes a compound sensitive to moisture, such that an exposure of the compound to moisture or wetting causes a physical and/or chemical change in the compound that is visually detectable in the cover material. A method of leak detection during vacuum bagging involves the steps of: arranging a component in a vacuum bagging assembly, such as to form a fiber-reinforced plastic component; arranging a material according to the invention in the vacuum bagging assembly such that the compound sensitive to wetting or moisture is under, or on an inner side of, a sealing film or vacuum bag of the assembly; applying a vacuum to the vacuum bagging assembly to evacuate a space containing the component and sealed by the sealing film or vacuum bag; and wetting an outer surface of the sealing film or vacuum bag.

    Abstract: An assembly for producing a fiber composite workpiece having a base tool, including a first tool part and a second tool part, arranged relative to one another either in a closed position in which they enclose an internal space, or in an open position wherein a preform can be mounted in the internal space and maintained there in a predetermined shape. The base tool includes a connection to convey matrix material into the internal space, and has a device for holding the first and second tool parts together in a closed position. A tool insert is provided which is separate from the base tool, the tool insert being mounted in the internal space of the base tool, and the tool insert including a cavity for accommodating a preform and a shaping surface, facing the cavity, for maintaining the preform in a predetermined shape.

    Abstract: A system for liquid composite moulding includes a first rigid tool part onto which a semi-finished fiber material is positioned, a first vacuum foil arrangeable on the first rigid tool part to provide a first gastight chamber therebetween having a first port, a second vacuum foil and the first vacuum foil providing a second gastight chamber, and granulated material arranged in the second gastight chamber. The semi-finished fiber material is infusible with a matrix material via the first port. A second port is provided at the second gastight chamber for applying a negative pressure thereto. Therein, the granulated material is adapted for forming a second rigid tool part when negative pressure is applied to the second port. I.e. the first vacuum foil, the second vacuum foil and the granulated material function similarly to a vacuum mattress and may be stiffened and collapsed.

    Abstract: A method of using solid profile rods instead of the usual filament coils for additive manufacturing methods such as 3D printing for industrial applications such as aircraft manufacturing, and to enable a more rapid production of fiber-composite components. The additive manufacturing device, or the 3D printer which generates the component layer by layer, respectively, comprises a material magazine in which a plurality of profile rods are stored. The profile rods are pre-tailored and are adapted to the component layer by layer. The profile rods, when printing, are successively retrieved from the material magazine and, by way of an infeed installation, guided to the nozzle of the additive manufacturing installation and subsequently applied to the printing bed so as to form the component layer by layer.
