Patent number: 11970023Abstract: A vehicle wheel arrangement includes a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for arrangement of a power-transmitting unit. In a joined state of the vehicle wheel arrangement a joining portion of the wheel hub corresponds with a joining portion of the carrier element. In the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of a wheel hub axis. The wheel hub includes, in a region of the joining portion, one or more fiber plies with fibers arranged unidirectionally in the circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub made of fiber-reinforced composite and a carrier element.Type: GrantFiled: November 12, 2018Date of Patent: April 30, 2024Assignee: ACTION COMPOSITES GMBHInventors: Jens Werner, Michael Dressler, Florian Franke, Christian Köhler, Michael Franke, Sandro Mäke, André Bartsch

Patent number: 10479031Abstract: The invention relates to a method and a device for infiltrating a fiber preform of a component of fiber composite material with a matrix material. On the method side, it is proposed that an elastic coating (3) is applied onto the fiber preform (1, 23, 37), wherein the elastic coating (3) is widened to form a gap space (22) between the fiber preform (1) and the coating (3). The matrix material (21) is then fed into the gap space (22) and the elastic coating (3) is subsequently pressed against the fiber preform (1, 23, 37). On the device side, it is claimed that an elastic coating (3) is arranged on the fiber preform (1, 23, 37) and means are provided, which are in operative connection with the elastic coating (3), by which the coating (3) can be widened while forming a gap space (22) between the fiber preform (1, 23, 37) and the coating (3). A matrix material (21) can be fed into the gap space (22) and the coating (3) can be pressed against the fiber preform (1, 23, 37).Type: GrantFiled: December 6, 2013Date of Patent: November 19, 2019Assignees: THYSSENKRUPP FEDERN UND STABILISATOREN GMBH, THYSSENKRUPP AGInventors: Werner Hufenbach, Martin Lepper, Jens Werner, Christian Koehler, André Bartsch

Patent number: 10265892Abstract: A mold system for a resin transfer molding process is presented, in which a cavity of a workpiece (1) to be produced is fully enclosed circumferentially by a multi-part shaping mold (2). The shaping mold (2) is enclosed in a sealed manner by an outer, two or more part enveloping mold (7, 8). A method for consolidating a fiber composite component with this mold system and a method for producing a fiber composite component on the basis of the RTM process is provided, in which the intermediate space between a shaping mold (2) and a surrounding enveloping mold (7, 8) is filled with resin during the resin injection. After curing the resin initially remains on the shaping mold (2) as a resin body but is destroyed during the demolding of the workpiece (1), at predetermined breaking points. The demolding of the workpiece (1) from the shaping mold (2) is assisted.Type: GrantFiled: August 22, 2014Date of Patent: April 23, 2019Assignee: THYSSENKRUPP CARBON COMPONENTS GMBHInventors: Sandro Mäke, Jens Werner, André Bartsch, Michael Dressler, Christian Köhler
