Beschreibung
Zusammenfassung:	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 +Θ or −Θ to the circumferential axis of the rim portion, wherein Θ is from 26° to 40°.
