HOLLOW SOLID GENERATED BY ROTATION AND METHOD FOR MAKING SAME

摘要

The invention concerns a hollow solid (1) generated by rotation whereof the wall comprises a first inner zone (a) made, at least on its outer periphery, of a single thermoplastic material A, and a second zone comprising a first part (b) arranged continuously with the first zone (a) and made of a thermoplastic material identical with material A and continuous glass yarns embedded in said thermoplastic material and a second part (c) forming the hollow body outer periphery and made only of thermoplastic material. The invention is characterised in that the wall has a vacuum volume proportion VV less than 0.5 %, preferably less than 0.2 %.
