Abstract
The present invention relates to a process for producing a hollow body of fibre-reinforced thermoplastic, and an arrangement for performing the process. In the process a continuous fibre bundle (3) is transported from means of transport (2). A section of the continuous fibre bundle (3) is heated up and the fibres in the section are impregnated with a thermoplastic. The impregnated fibre section is applied to a core-moulding tool (6), capable of controllable rotation about a shaft and located in an oven (5) with separate temperature control (5a). The angle or rotation of the core-moulding tool, together with the axial application position of the fibre section and the rate of feed of the fibre section are controlled in order to produce a hollow body with a pre-determined configuration on the core-moulding tool (6). The oven temperature is also controlled so that the thermoplastic on the core-moulding tool (6) is viscous during application. The tension in the fibre section is also controlled so that the fibres remain continuous and essentially extended whilst the process is being carried out. Application to the core-moulding tool (6) is terminated when the hollow body has taken on a pre-determined configuration, following which the rate of cooling of the hollow body is controlled by means of a separate temperature control for the oven (5a).
