| 摘要 |
The invention relates to a method for producing a part comprising a hollow body made from a composite material, using preforms (11, 12), said method including the following steps: a step in which the preforms are disposed around a suitable supporting element (1) such that the coupling edges of each preform (11, 12) overlap, and come into contact, with a coupling edge of another preform (12, 11); a step in which the coupling edges of each preform are joined along a seam; and a step in which the supporting element is removed and a mould core is inserted in its place before the assembly is placed inside a mould and resin is injected using an RTM/LRI method, prior to the polymerisation of said resin.
