Abstract

La présente invention a pour objet des procédés et dispositifs pour fabriquer des corps creux en résine stratifiée à partir de manchons textiles préimprégnés. Un procédé selon l'invention comporte trois étapes successives. Dans une première étape, on préforme les manchons 2 en les enfilant séparément sur un mannequin mâle et en les retirant Dans une deuxième étape, on habille un moule 6 en enfilant les uns sur les autres les manchons préformés 2n, 2n+1 etc. Dans une troisième étape on polymérise la résine par tout moyen connu Une application est la fabrication de corps creux en résine stratifiée tels que réservoirs, radômes, coques, éléments de tuyauterie, etc
