The invention concerns a method for making floating objects and pleasure boats, as well as mandrels and machines for said manufacture. More particularly the invention concerns a method for making floating objects, such as boat hulls or part of such a hull, characterised in that it comprises at least a step of filament winding. Said method comprises the combination of steps for producing at least one mandrel with a substantially internal and/or external shape of the floating object to be made, and for winding it so as to obtain a floating object and/or its outer countermould. The mandrel of the floating object to be made and/or the countermould mandrel (1) provide grooves and/or raised devices and/or devices for increasing adherence between the mandrel and the fibres for winding and/or at least for providing a structural member. The step for covering the mandrels (8) and or (1) is characterised in that it comprises a phase which consists in depositing at least a continuous fibre impregnated with resin or not, along directions predetermined during the designing of the floating object and/or the countermould so as to obtain at least a layer of fibres. The floating object is characterised in that it comprises at least part of a hull and/or of a deck made by said method.
Procédé de fabrication de corps flottants et embarcations nautiques, mandrins et appareils pour cette fabrication. L'invention concerne notamment un procédé de fabrication de corps flottants, tels que coque de bateau ou partie d'une telle coque, caractérisé en ce qu'il comporte au moins une étape d'enroulement filamentaire. Ce procédé comporte la combinaison d'étapes prévoyant de réaliser au moins un mandrin présentant sensiblement la forme interne et/ou externe du corps flottant à fabriquer, et de le bobiner afin d'obtenir un corps flottant et/ou son contremoule externe. Le mandrin du corps flottant à fabriquer et/ou le mandrin (1) du contremoule prévoient des rainures et/ou des dispositifs en relief et/ou des dispositifs permettant une augmentation de l'adhérence entre le mandrin et les fibres, permettant de bobiner et/ou de disposer au moins un organe de structure. L'étape de recouvrement des mandrins (8) et/ou (1) est caractérisée en ce qu'elle comporte une phase de dépose d'au moins une fibre continue imprégnée ou non de résine, suivant des directions prédéfinies lors de la conception du corps flottant et/ou du contremoule, afin d'obtenir au moins une couche de fibres. Le corps flottant est caractérisé en ce qu'il se compose d'au moins une partie de coque et/ou d'un pont fabriquée par ce procédé.
