  • Patent number: 8597560
    Abstract: A method for manufacturing (partly) ring-shaped components, which include fiber-reinforced plastic, from fiber-composite semifinished products, involving the steps of: positioning a multitude of ring-shaped or partly ring-shaped mold pieces on a rotatable drum in such a manner that they include a reel-shaped mold with a ring-shaped channel for receiving the semifinished product, applying the semifinished product in the channel of the ring-shaped mold, rotating the drum in such a manner that as a result of the centrifugal forces the matrix material is pressed towards the outside and air contained in the channel moves inwards, and curing the semifinished product with the application of temperature to form a plastic ring, removing the plastic ring from the ring-shaped mold.
