<p>The invention concerns a method of forming preforms to manufacture fibre composites, comprising monoaxial or biaxial laid-yarn fabrics, which are injected with a thermosetting plastic or a thermoplastic material or - if the fabric is made from a thermoplastic hybrid yarn - are heated. According to the novel method, the fabric material is applied on a core (5), which is an elongate body, in the form of ribbons (1, 2, 3, 4). These are advanced at an angle relative to the core (5) and are wound onto the latter in overlapping relationship, preferably by rotation of the core (5) about the longitudinal centre core axis while said core is simultaneously being advanced in its longitudinal direction.</p> |
