Abstract

Boat hull surfaces are finished by (1) premixing the surface, (2) applying on the surface a nylon fabric which has been treated with an antistick agent, (3) impregnating the fabric with a suitably catalysed synthetic resin, (4) polymerising the resin and (5) peeling the tissue from the surface. The method is esp. for finishing the outer surfaces of moulded sailing boat hulls. It avoids the use of conventional premixing and polishing. It gives a textured surface with relief prints, the choice of resin giving surfaces having resistance to abrasion, corrosion and heat. The texture improves fluid flow and allows an antiskid coating to be obtd.

Description

La présente invention a pour but de simplifier la finition des coques d'engins nautiques et, en particulier, celle des planches à voile fabriquées"sur mesure". Dans ce type de fabrication, l'état de surface final est obtenu par ponçage avec des abrasifs de plus en plus fina, puis polissage à la peau de mouton avec des liquides à polir. The object of the present invention is to simplify the finishing of the hulls of nautical devices and, in particular, that of windsurf boards made "to measure". In this type of manufacturing, the final surface finish is obtained by sanding with more and more fine abrasives, then polishing with sheepskin with polishing liquids.

Cette opération est longue, délicate, et nécessite une bonne habileté manuelle. Par ailleurs, le polissage fait res- sortir les petits défauts éventuels. This operation is long, delicate, and requires good manual skill. In addition, polishing brings out any small faults.

Le procédé décrit ici permet d'obtenir un aspect de surface dépoli qui évite toute reprise ultérieure. The process described here makes it possible to obtain a frosted surface appearance which prevents any subsequent recovery.

Le mode opératoire est le suivant t
On ponce la surface à traiter.The operating mode is as follows t
We sand the surface to be treated.

Bn pose sur cette surface un tissu nylon dont les fibres sont traitées avec un agent anti adhérent. Bn places a nylon fabric on this surface, the fibers of which are treated with a non-stick agent.

On impregne ce tissu d'une résine synthétique convena-blement catalysée. Après polymérisation, on enrache ce tissu de la surface ; sa texture reste imprimée en creux. This fabric is impregnated with a suitably catalyzed synthetic resin. After polymerization, this fabric is wrapped around the surface; its texture remains imprinted.

Le choix de la résine permet d'obtenir des surfaces résistant à l'abrasion, à la corrosion,,à la chaleur. The choice of resin makes it possible to obtain surfaces resistant to abrasion, to corrosion, to heat.

Le choix de la texture du tissu permet d'obtenir un dessin ou un aspect déterminé. The choice of the texture of the fabric makes it possible to obtain a determined design or appearance.

Outre la suppression des opérationsBe finition toujours délicates, l'utilisation d'un tel proc4d permet d'obtenir une amélioration sensible de l'écoulement. de l'eau sur la surface. In addition to the elimination of always delicate finishing operations, the use of such a process makes it possible to obtain a significant improvement in the flow. water on the surface.

Lorsque les vitesses de déplacement d'une surface sur un fluide sont importantes, l'écoulement est successivement malinaire, turbulent puis tourbillonnaire.. When the speeds of movement of a surface on a fluid are high, the flow is successively malinary, turbulent then vortex.

L'iért-at de surface obtenu par l'utilisation d'une toile nylon taffetas de 20 fils de 30 bouts au centimètre permet d'arriver à untel résultat. L'état dewsurface ainsi obtenu est également antidérapant et ceci de façon très efficace. The surface interest obtained by the use of a nylon taffeta canvas of 20 threads of 30 ends per centimeter allows to achieve such a result. The surface condition thus obtained is also non-slip and this very effectively.

On peut, en fonction des gradients de pression relevés sur une coque, utiliser a l'avant et à l'arrière des textures différentes et privilégier sur toutes les surfaces planes l'emploi de fils de chaine plus gros que les fils de trame pour obtenir des stries longitudinales parallèles au sens du déplacement qui conditionnent le mpuvement de l'eau.  We can, depending on the pressure gradients recorded on a shell, use different textures at the front and rear and favor the use of warp threads larger than the weft threads on all flat surfaces to obtain longitudinal ridges parallel to the direction of movement which condition the movement of the water.

Sa simplicité de réalisation permet également une application à posteriori sur toutes les coques dont on désire améliorer les caractéristiques. Its simplicity of realization also allows an application a posteriori on all the hulls whose characteristics one wishes to improve.

Le dessin en relief peut en outre être obtenu avec toutes les peintures marines antifouling qui sont couramment utilisées.  The relief drawing can also be obtained with all the antifouling marine paints that are commonly used.
