A method and device for manufacturing a body, a device for implementing the method, and products obtained by the method. In the method, at least a first heated composite strip is introduced into at least one die, and at the same time, at least one molten material is introduced into the die in contact with the first composite strip, to obtain at least one second composite strip, and the second composite strip is wound around a support rotating about its axis.

Method and device for producing a hollow body by rotation and resulting products

Method for sealing a bared section ( ) in the wall of a hollow body based on a thermoplastic and on reinforcing fibers, the hollow body being especially intended for conveying or containing a pressurized fluid. The surface and the contours of the section ( ) are coated with a protective thermoplastic ( ) which is heated while it is being deposited and is compatible with the said thermoplastic of the hollow body in order to achieve complete adhesion.

Method for sealing a bared section of the wall of a hollow body made of a composite based on a reinforced thermoplastic

The present invention relates to a hollow body of revolution ( ), 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 V of less than 0.5%, preferably less than 0.2%.

Method for making hollow solid generated by rotation

A process for manufacturing composite sheets. The sheets are made of at least one ply of yarn with this ply having at least two materials with different melting points. The ply is introduced continuously into a zone where it is heated to a temperature between the two melting points and below the degradation temperature of the material having the lower melting point. This ply is then passed over at least one rotating bar heated to a temperature lying between the melting points and below the degradation temperature of the material with the lower melting point. The ply is then compressed on leaving the rotating bar and is cooled to form a composite web. The web is collected in the form of one or more composite plies.
