ABSTRACT:
Apparatus for molding a fiber-reinforced wheel construction having an imperforate disc structure. The wheel comprises a disc portion having reinforcing fibers in substantially random orientation disposed predominantly in planes perpendicular to the wheel axis, and a rim portion having directional first reinforcing fibers substantially parallel to each other and oriented circumferentially of or substantially parallel to the wheel axis, or both, and second reinforcing fibers which are substantially randomly oriented circumferentially of the wheel axis. An apparatus for molding the wheel features radially movable rim mold sections and axially reciprocable disc mold sections all having mold surface contours for forming a molded composite wheel of desired configuration.
