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

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;.
