Definitions

  • the present invention generally relates to a rim component of a composite wheel and an edge arrangement thereof.
  • the invention is particularly applicable to composite carbon fibre wheels for vehicles and/or aeroplanes and it will be convenient to hereinafter disclose the invention in relation to that exemplary application.
  • the invention is not limited to that application and could be incorporated into the rim configuration of a large variety of wheels.
  • the Applicant has produced a one-piece composite wheel, which is described, for example, in International Patent Publication WO2010/024495A1 .
  • the Applicant's composite wheel generally includes two main sections, a rim portion and a face portion.
  • the rim portion comprises an annulus structure configured to receive and seat a tyre.
  • the face portion includes a hub which is used to fix the wheel to the vehicle, and a connection structure such as series of spokes or a disc which extends between and interconnects the hub and the rim. Lateral, vertical and torsional loads are transmitted through the tyre to the rim portion of the wheel which then produce bending and torsional stresses in the connection structure.
  • the rim portion of a composite wheel typically comprises a generally cylindrically shaped rim body having two flanged annular edges, each flange having an outside surface including an annular bead located at the edge.
  • the reinforcement of the rim portion is conventionally laid up as stacked layers of reinforcement fabric in the rim body, the flanged edges and the annular bead.
  • the layered structure typically terminates with the ends of the layers extending from a section of the flanged edges.
  • the stacked structure of the layer ends at the flanged edges can therefore have a rough and uneven finish. Consequently, it has been standard practice to machine the composite rim structure at the edge of the inner bead after removing the part from the mold tool to provide a more even finish.
  • the present invention therefore provides a rim component of a composite wheel where the annular edges including the exposed ends of the layers of reinforcement fibres are covered by a layer of reinforcement. This arrangement results in that edge being molded to the final shape of that annular edge after a matrix material, such as resin is impregnated/ introduced into the component. No subsequent machining of the reinforcement is therefore necessary to provide an acceptable finish.
  • the capping layer provides a substantially continuous cover over the respective annular edge and the exposed ends of all internal fibre reinforcement layers, so that no fibre ends are exposed.
  • the continuous cover also ensures a molded surface is produced once the matrix material is introduced, so that subsequent machining processing is not required. It is noted that any advantages provided by the present invention would be negated if subsequent machining processing is used on that annular edge, as this would involve cutting fibres at this location thus exposing cut fibres or creating delamination between fibre layers in the rim.
  • the rim body preferably comprises a generally cylindrically shaped body.
  • the rim body includes at least one flange at or proximate the annular edge thereof, preferably forming two flanged annular edges.
  • the rim body typically has an outside annular surface and an inside annular surface extending between the annular edges.
  • the capping layer extends over at least a portion of the inside annular surface and the outside surface of the rim body.
  • the rim body, and/or in applicable embodiments, the flanged annular edges can include at least one first annular bead located at or proximate at least one annular edge.
  • the capping layer preferably extends over the first annular bead.
  • the rim body includes at least one second annular bead axially spaced apart from the first annular bead, the capping layer extending at least to the second annular bead.
  • the first and second annular beads are preferably located on the outside annular surface of the rim body.
  • the rim portion is laid out with a layered structure.
  • the number of layers may vary considerably depending on the design and size of the various sections of the rim component. In some embodiments, only a few layers, for example 2, 3, 4, 6 or 10 are used. In other embodiments, a higher number of layers, for example 20, 30, 50, 100 or more are needed to obtain the desired quality and/or properties of the rim component.
  • the layer structure preferably comprises a plurality of stacked layers. Within each layer of the layer structure preferably comprises a substantially coplanar arrangement of reinforcement fibres.
  • the reinforcement fibres may be provided in any desirable orientation in the rim body and capping layer, including but not limited to unidirectional, biaxial or random.
  • Each reinforcement layer in the body portion preferably comprises oriented reinforcement fibres, preferably unidirectional fibres or biaxial reinforcement fibres.
  • the capping layer also preferably comprises oriented reinforcement fibres, preferably unidirectional fibres or biaxial reinforcement fibres. It should be noted that the orientation of the reinforcement fibres in the capping layer may be the same, or different to the orientation of the reinforcement fibres in the body portion.
  • the reinforcement fibres are preferably oriented to reduce the stress with the rim component and/or reduce the stress between the rim component and any connected component (such as the disc portion of a composite wheel) as well as to strengthen areas of the final structure which will be exposed to a higher stress during service.
  • the orientation of reinforcement fibres may or may not be the same in all the layers of the body portion.
  • one or more layers of reinforcement fibres may be oriented in another manner than other layers, if a stress analysis suggests a multi-axial fibre orientation.
  • the reinforcement fibres may be oriented substantially the same way in all the layers of the body portion of the rim component.
  • the reinforcement fibres may be provided in any suitable form including in prepregs, semi-pregs, woven or non-woven fabrics, mats, pre-forms, pre- consolidated pre-forms, individual or groups of fibres, tows, tow-pregs, or the like.
  • the matrix material such as resin
  • the matrix material need not be comprised in the layers comprising reinforcement fibres (e.g. a prepreg or semi-preg) or between the layers comprising reinforcement fibres.
  • the matrix material should form a continuous matrix after the curing.
  • the matrix material need not be comprised in or between two adjacent layers com- prising reinforcement fibres.
  • an adhesive may in this case be provided between at least some of such pairs of layers to at least temporarily and at least partially fix the adjacent layers comprising reinforcement fibres.
  • prepreg refers to a substantially or fully impregnated collection of fibres, fibre tows, woven or non-woven fabric or the like.
  • semi-preg refers to a partially impregnated collection of fibres or fibre tows. The partial impregnation provides for enhanced removal of gas through or along the dry fibres during consolidation and/or curing.
  • An example of a semi-preg is a partially impregnated layer of fibres.
  • woven and non-woven fabrics are collections of individual fibres or fibre tows which are substantially dry, i.e. not impregnated by a matrix material, for example resin. It should also be understood that fibre tows are bundles of a large number of individual fibres, for example 1000's, 10000's or 100000's of fibres. Tow-pregs are at least partially impregnated fibre tows.
  • Sections of the rim component may be prepared as a pre-form.
  • one or more of the sections of the rim component are formed into a tailored fibre preform having a desired shape and fibre orientation.
  • a pre-form is a composite material comprising reinforcement fibres, and typically, an uncured resin.
  • the reinforcement fibres are preferably provided in layers of oriented fibres, for example individual or groups of fibres, fibre tows, fibre tow-pregs, prepregs, semi-pregs, woven or non-woven fabrics or mats.
  • the reinforcement fibres of the rim body and/or the capping layer are provided as at least one fabric sheet or ply, and more preferably as at least one multi-axial fabric sheet or ply.

  • the matrix material comprises a resin.
  • the fibres of the rim component are preferably injected and/or impregnated with resin and then cured.

  • the resin is epoxy-based.
  • the matrix material comprises a metal or composite metal material.
  • the fibres of the rim component are preferably injected and/or impregnated with a metal or metals, forming a composite metal matrix with the fibres when set.
