A shaped preform component (A) for a spoke portion (A) of a composite wheel (), the shaped preform (A) comprising: an elongate body () configured to be located in a spoke () of a composite wheel (), wherein the shaped preform component (A) is formed from a cured composite fibre material having a compressibility of <2% volumetric under moulding conditions of 50 bar hydrostatic pressure and a temperature of 60 to 150° C., and wherein the density of the cured composite fibre material is selected to form a counterbalance mass for a mass addition () to the composite wheel ().

Shaped preform for spoke portion of a composite wheel

The invention relates to a composite wheel () including a hub (), a rim () and a connection structure () connecting the hub () to the rim (). The hub () has front () and rear () faces and is formed with one or more mounting formations () for, in use, receiving a fastener to mount the hub () to a mounting surface of a vehicle. Each mounting formation () includes a fastening region () recessed into the front face () of the hub () and includes a fastener aperture () defining a passage between the fastening region () and the rear face () of the hub. Each mounting formation () also includes a front-to-fastener ply () extending between a front region of the hub and the fastening region () for, in use, transferring load between the front region of the hub () and the fastening region ().

Composite wheel with improved mounting formation

A rim portion of a composite wheel comprises a shaped annulus formed about a central axis of rotation of the composite wheel and having a circumferential axis extending circumferentially about the central axis and around the rim portion, said rim portion having a fibre layup comprising a stacked laminate formed from alternating layers of: a hoop tow layer comprising elongate fibre tow in which the fibres are substantially aligned with the circumferential axis of the rim portion, the hoop tow layer being formed from at least one annularly wound elongate fibre tow; and a bias ply layer comprising at least one fibre ply in which the fibres are substantially orientated at an angle of +&#x398; or &#x2212;&#x398; to the circumferential axis of the rim portion, wherein &#x398; is from 26&#xb0; to 40&#xb0;.
