  • Patent number: 10710399
    Abstract: Disclosed is a vehicle wheel having a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc is connected to the wheel rim by a connecting element which is guided through a through-hole of the rim base and inserted in the wheel disc. The through-hole is arranged in the tire seat of the rim base and the connecting element is joined substantially in the direction of the radial extension of the wheel disc which is associated to the tire seat on the inner side of the rim. In the method for producing the wheel the connection between wheel rim and wheel disc is produced in the region of the tire seat of the rim base, and, after the insertion of the connecting element into the wheel disc, a portion of the connecting element protruding the contour of the outer side of the rim of the tire seat is shaped so that the connecting element conforms to the contour of the outer side of the rim of the tire seat.

  • Patent number: 10479031
    Abstract: 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).

  • Patent number: 10265892
    Abstract: 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.
