Abstract:
1. A method for manufacturing a fibre-reinforced-plastic-containing ring-shaped or partly ring-shaped semifinished product or component from fibre-composite semifinished products, including the steps of: (a) positioning at least one ring-shaped or partly ring-shaped mould piece on a rotatable drum in such a manner that the latter comprises a reel-shaped mould with a ring-shaped or partly ring-shaped channel section that extends in an outward radial direction, and in a longitudinal direction, of the drum, (b) multilayer application of semifinished product material in the channel section of the reel-shaped mould, (c) at least one repetition of steps (a) and (b) with the addition of at least one ring-shaped or partly ring-shaped mould piece on the rotatable drum while forming a further channel section that continues on from the existing channel section, and placement of semifinished-product material in the channel section, wherein a created sequence of channel sections at least in part provides the mould for the component to be manufactured, (d) placing matrix material in the channel sections with the insertion of semifinished-product material in individual channel sections and after forming at least one channel section, (e) after forming the channel sections with semifinished product material and matrix material contained therein, 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 is displaced radially inwards, (f) curing the matrix material contained in the channel, (g) after curing the ring-shaped semifinished product or component, separating the mould pieces into sections, and removing the cured ring-shaped semifinished product or component, wherein at least two mould pieces are designed in such a manner that they interact in a positive-locking manner, via a projection and groove arrangement, so that one of the at least two mould pieces is situated on, and affixed to, an outside of another of the at least two mould pieces in the radial direction of the drum so that a sidewall, directed in the axial direction, of the one mould piece forms a sidewall of a channel section.
