    摘要: The method involves producing removable cores (26-29) into core molds, and applying bar-preforms (30-32) formed with reinforcing carbon fibers on the cores for forming reinforcing elements and arranging the cores at a common structure (23). The cores are supplied with web-like semi-finished products for creating an external shell (33). The common structure is inserted into a closed molding tool and filtered with hardenable plastic material. A fiber composite part is hardened by utilizing pressure and/or temperature, and the cores are removed. An independent claim is also included for a core mold for executing a method for producing an integral fiber composite part.

    摘要: The invention relates to a load introduction system (1) comprising an aerodynamic component (10) having a skin section (12) with an outer surface (14) and a first protrusion (16), and an attachment unit (20) for movably coupling the aerodynamic component (10) to a base unit (30). The attachment unit (20) is attached to the skin section (12) of the aerodynamic component (10) and to the first protrusion (16), wherein the first protrusion (16) extends away from the aerodynamic outer surface (14), thereby separating a space adjacent the aerodynamic outer surface (14) into a front space (16a) and a rear space (16b). The attachment unit (20) extends over the first protrusion (16) such that the attachment unit (20) comprises a front portion (21) in the front space (16a) and a rear portion (22) in the rear space (16b). The invention also relates to a method for manufacturing a load introduction system (1).

    摘要: The present invention relates to a method for treating an object (19, 119) manufactured from a material having a defined melting temperature and to a corresponding apparatus. The object (19, 119) is subjected to hot isostatic pressing for reducing the porosity and increasing the density thereof, comprising arranging (202) the object (19, 119) inside an interior cavity (6, 106) of a pressure chamber (2, 102), submerging (203) the object (19, 119) in a liquid disposed inside the cavity (6, 106) and partially filling it, heating (204) the liquid to a first temperature below the melting temperature, pressurizing (205) the liquid by providing pressurized gas in a portion (12, 112) of the interior cavity (6, 106) above a free liquid surface (18, 118), maintaining (206) the object (19, 119) inside the liquid, and arranging (207) the object (19, 119) outside the liquid in a portion (12, 112) of the interior cavity (6, 106) above the free liquid surface (18, 118). Subsequently the liquid is heated (208) to a second temperature above the melting temperature, and then the object (19, 119) is moved (209) from a portion (12, 112) of the cavity (6, 106) above the free liquid surface (18, 118) into the liquid and submerged again therein for reducing its surface roughness. Subsequently, the object (19, 119) is withdrawn (210) from the liquid and moved into a portion (12, 112) of the interior cavity (6, 106) above the free liquid surface (18, 118). The apparatus comprises the pressure chamber (2, 102), a movable support arrangement (13, 113) in the cavity (6, 106) for supporting the object (19, 119), a heating means (10, 110) for heating the liquid, and a gas inlet and outlet through which gas can be selectively introduced into the interior cavity (6, 106) and vented from the interior cavity (6, 106).

    摘要: Verfahren zur Herstellung eines integralen Faserverbundbauteils (104), insbesondere einer aerodynamischen Wirkfläche, mit einer Vielzahl von mit einer Außenhaut (106) umschlossenen Versteifungselementen (107).
    Das erfindungsgemäße Verfahren erlaubt die Herstellung eines komplexen, integralen (einstückigen) Faserverbundbauteils mit einer Vielzahl von innenliegenden und hinterschnittenen Versteifungselementen (107) unter Verwendung von lösbaren Kernen (11-13,26-29,56,75). Dadurch, dass keine Verbindungselemente mehr erforderlich sind, ergibt sich ein hohes Gewichtseinsparungspotential, da beispielsweise Nieten und hierfür notwendige Nietflansche, wie im Fall einer konventionellen Montage aus Einzelteilen (differentielle Bauweise), überflüssig werden.
    Die Kernformen (1,68) zur Durchführung des Verfahrens können auf einfache Weise an variierende konstruktive Anforderungen angepasst werden, ohne dass aufwändige Korrekturen an dem für den RTM-Prozess eingesetzten Stahlwerkzeug notwendig sind.
