Tubular body of plastics with fibre reinforcement

摘要

To produce a tubular moulded body of plastics with a fibre reinforcement, a fibre strand with a reaction resin is wound in a spiral round a core formed by an inflated film tube. The fibre strand is wound round the core while the core does not rotate but is advanced axially. The fibre strand is a roving, woven roving, mat or non-woven of glass or polyester fibres, to be impregnated with a reaction resin.
