<p>Method for compacting wound resin-impregnated fibrous materials consists of these stages: (a) one winding turn is formed around a mandrel, (b) successing turns are formed upon one another, each being compressed by a suitable tensioned band which is removed before the next winding is produced, (c) the final winding of fibrous material and resin is combined with a heated tensioned band and (d) the assembly is hardened, after which the mandrel and tensioned band are removed. Pref. fibres are carbon, boron or glass, alternatively in the form of bands. The first tensioning band may be of plastics, the second, heated tensioning band, of metal. The method enables the fibres to be compacted to high density without crumpling.</p> |
