Abstract: 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 +? or ?? to the circumferential axis of the rim portion, wherein ? is from 26° to 40°.

Abstract: A carbon fibre vehicle wheel including a wheel body having a rim portion and a face portion, the rim portion having an annulus structure configured to receive and seat a tyre. The face portion includes a hub configured to fix the wheel to the vehicle. A connection structure extends between and interconnects the hub and the rim. The wheel body has an inner side configured to face a wheel mount of the vehicle, and an outer side configured to face outwardly when connected to the wheel mount. The wheel body embodies a first carbon fibre composite composition including a carbon fibre layup infused with a first resin, and a fascia layer attached to at least a portion of the face portion of the outer side of the wheel body. The fascia layer embodies a second fibre composite composition including a selected fibre layup infused with a second resin.

Abstract: A fluid reticulation system for a composite component production assembly, the production assembly including at least one pressure chamber (25) having a chamber wall (21) locatable adjacent a composite lay-up or mold, at least a portion of the chamber wall (21) being resiliently deformable, the fluid reticulation system being locatable within the inner volume of the pressure chamber (25) and including means (5) for distributing fluid towards an inner surface (22) of the chamber wall as the fluid enters the pressure chamber.
