Rotomoulding procedure for making composition products uses mesh or fabric of composition filaments over inflatable pouch

The procedure uses an inflatable pouch (1) in a mould (4), covered with a layer (3) of interwoven composition fibres and heated before being inflated, so that the fibre layer is formed to the shape of the mould. The interwoven fibres can be in the form of a knitted or woven fabric and can incorporate a supplementary material such as an organic material in powder form. The procedure uses an inflatable pouch (1) in a mould (4), covered with a layer (3) of interwoven composition fibres and heated before being inflated, so that the fibre layer is formed to the shape of the mould. The interwoven fibres can be in the form of a knitted or woven fabric and can incorporate a supplementary material such as an organic material in powder form. The pouch is partially inflated before the fibre layer is positioned, and is inflated to a pressure of 0.3 - 5 bars during moulding. The apparatus used for the procedure consists of at least one mould able to rotate about at least one axis (8, 10), at least one mould heater (9), and at least one inflation system for the pouch(es). La présente invention concerne un procédé de fabrication de produits composites par rotomoulage, selon lequel on chauffe, dans un moule en rotation, au moins une poche gonflable revêtue d'au moins un réseau de fils entrecroisés composite, et on gonfle ladite poche afin que ledit revêtement prenne la forme du moule.L'invention concerne également un dispositif de mise en oeuvre du procédé et les produits obtenus.
