Abstract: The present invention relates to a hollow body of revolution (1), the wall of which comprises an internal first region (a) made, at least on its external periphery, of a single thermoplastic organic material A, and a second region having a first part (b), arranged so as to be continuous with the first region (a) and made of a thermoplastic material identical to the material A and of continuous glass yarns embedded in the said thermoplastic material, and a second part (c) forming the external periphery of the hollow body and made only of thermoplastic material. According to the invention, the wall has a volume void content Vv of less than 0.5%, preferably less than 0.2%.

Abstract: Process for manufacturing a composite tape (10), consisting in bringing together and in consolidating a multiplicity of continuous yarns (11), characterized in that yarns (11) based on a thermoplastic and on reinforcing fibers are entrained and brought together in a parallel manner in the form of a sheet (12) which enters a zone in which it is heated to a temperature reaching at least the melting point of the thermoplastic and then passes through a rotating impregnation device (80) in order to distribute the molten thermoplastic uniformly and guarantee that the reinforcing fibers are completely impregnated by the latter; next, the sheet (12) is introduced into a shaping and centering device (100) so as to obtain a tape (13) formed by bringing the yarns (11) together so as to be touching, thereby creating transverse continuity; the tape (13) is cooled in order to consolidate the yarns by freezing the thermoplastic and its dimensional characteristics and its appearance are set in order to deliver the said compo
