Abstract

A method of making a cylindrical or prismatic hollow object of fibre-reinforced plastics is as follows: preimpregnated fibres are supplied longitudinally onto a revolving mandrel so that they lie axially along it; a second series of preimpregnated fibres is wound helically, opt. with overlay, around this first set as the mandrel revolves, until the desired wall thickness has been built up; the outer surface is pressed and smoothed to remove concealed air bubbles; the external dimensions are checked and corrected where necessary; the prodt. is advanced through a polymsn. heater, is finally hardened, is advanced and cut off into suitable lengths. For the industrial mfr. of reinforced hollow prismatic or cylindrical objects from polymerisable plastics. The method eliminates the disadvantages of using a mould for the batch prodn. of articles in succession.
