  • Patent number: 9555664
    Abstract: A wheel with a rim as well as a wheel spider, where the wheel spider has a hub and spokes. The wheel includes spokes including one or more linearly stretched textile strands as reinforcement material of a fiber composite and each linearly stretched textile strand runs at least once from the rim to the hub and back without interruption and thus forms at least one spoke. The textile strands are connected in a positive-locking manner and/or in substance with the hub and the rim. A process is provided for the manufacture of the wheel.

  • Patent number: 9539855
    Abstract: A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

  • Publication number: 20160200018
    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.

  • Publication number: 20150343719
    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).

  • Publication number: 20150330471
    Abstract: The invention relates to a method for producing a spring made of fiber composite material, in which a laminate strand which is formed from fibers of fiber composite material and is impregnated with a matrix material that can be consolidated is reshaped into a spring geometry. The invention also relates to a device for carrying out the method. On the method side, it is proposed that, prior to reshaping the laminate strand (2), a strand-shaped pre-product (20) is formed by applying a deformable protective jacket (16), which encloses the laminate strand (2), in a continuous application process. On the device side, it is proposed that an application unit (15) for forming a protective jacket (16) around the laminate strand (2) is arranged downstream of the processing device (1) in the transport direction of the laminate strand (2).

  • Publication number: 20140375112
    Abstract: A one-part wheel which is made of fiber composites without interruption of fibers with excellent mechanical properties and with low weight at the same time as well as a process for the manufacture thereof. The wheel has especially a rim well as well as a wheel disk passing over into a wheel flange of the rim well, where the wheel disk is formed at least partly by fiber layers, which run from the rim well over a wheel flange and the wheel disk. The wheel is manufactured by a multipart mold with parts displaceable at least in the axial direction. The mold is completely removed after the deposition of fibers or remains as a lost core in the wheel.
