METHOD OF MOLDING A FIBRE-REINFORCED COMPOSITE WHEEL

摘要

A method of molding a fibre-reinforced composite wheel using a mold assembly. The mold assembly includes an annular rim mold portion for defining an outer surface of a rim of the wheel and a disc mold portion for defining a front surface of a disc portion of the wheel. The method comprises the steps of : locating at a first part of reinforcement fabric within the mold assembly around the rim mold portion; locating at a second part of reinforcement fabric within the mold assembly over the disc mold portion; sealing the mold assembly with a flexible mold element to form a substantially fluid tight mold cavity, the flexible mold element comprising a flexible polymer component for defining an inner surface of the rim of the wheel and a rear surface of the disc portion of the wheel; introducing a resin into the mold cavity by withdrawing air from the mold cavity through an inlet at a convenient location on the mold assembly; and curing the resin to form an integral fibre-reinforced composite wheel.
