Última Innovations and technical-economic aspects of structural and non-structural applications of composite materials on large passenger vessels and merchant ships. ArchiMer Maccari, A; Farolfi, F. Considerable interest is presently being shown in research, design and practical application of composite materials within Fincantieri Merchant Shipbuilding Division. This paper is intended to discuss the state-of-the-art and the innovations in hull, outfitting and accommodation applications, where traditional steel or light alloy can be successfully replaced by composites. The impact on design and production is outlined, with an overview of the economic effects of these materials on technology, production and safety requirements, which remain an open subject for the future possible developments.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1053.pdf La conception de structures navales en sandwich: Un probleme inverse ArchiMer Holm, D; Esping, B; Romell, O; Campion, F. An integrated approach is introduced for the solution of the inverse problem: which are the lamina orientation, laminate constitution, core quality and thickness combination ensuring specified objective(s) to be reached? The optimal solution is obtained using mathematically stringent optimization methods (the Method of Moving Asymptotes, MMA) coupled with finite element analysis, interactive graphic pre- and post-processing and parametric modelling, as implemented in OASIS-ALADDIN. This approach has been applied to the optimal design of the hull structure of a Surface Effect Ship made of GRP-sandwich. The objective was to minimize the weight of the ship by determining the optimum skin and core thicknesses of structural members of the hull as well as web...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1054.pdf L'analyse structurale par methode d'elements finis d'une coque en composite ArchiMer Simeone, M; Davies, Peter. In the last two decades, the Finite Element Method has been growing as a powerful tool for the structural analysis of the ship hull, but in nautical construction the use of this method has been related mainly to steel or aluminium hulls. In a metallic structure the material is homogeneous and isotropic and the plate, or the stiffened plate, behaves as an orthotropic plate, which means orthogonally anisotropic with three mutually perpendicular planes of symmetry; on the contrary, when considering a composite hull panel the scheme ought to be different, because there arise two different problems, which ensue from the structural characteristics of the composite sandwich panel. Firstly, the Element Stiffness Matrix must take into account the natural anisotropy...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1072.pdf Non-conventional vessels in Scandinavia made of composite materials. ArchiMer Gullberg, O. This paper presents the background to the development of composite materials in marine structures in the Scandinavian countries. The very first vessel constructed in composite materials in 1974 used a special sandwich technique, GRP sandwich, developed in Sweden. Since the the GRP sandwich technique has been the only ship hull construction method used in the Scandinavian countries. The construction method is briefly described, together with the material used. In the second part of the paper examples of the different types of vessels under construction are presented. Finally, in the conclusion some ideas of future development are outlined.
