GOMES, E. S. Computational routines for the calculation of geode sic paths in filament winding process. 2009. 121p. Master Thesis – Escola de Engenharia de São Carlos, Universidade de São Paulo, São Carlos, 2009 . Composite materials are well known by the high stre ngth and low weight, superior performance, resistance to the cor rosion and low density. The production of a composite material part involves so me processes with different requirements. The filament winding process is an au tomated process in which continuous reinforcement fibers are lay down in pre sc ibed paths on the surface of a mandrel, which is generally removed after the cure of the resin. In such a way, it is fundamental that the designer uses computational re sou ces for the calculation of the paths and sequence of the fibers. In this work is d eveloped the mathematical procedures for calculation of geodesic trajectories in the Fil ament Winding process and implements them in a computational environment in high level l anguage Java, considering the circumferential, helical and polar strategies. Two case studies are developed successfully: conical pipes and pressure vessels, a nd the results presented and discussed, validating the procedures and implemented environme nt. Key-words: Filament winding, Composites, Geodesic paths, Tube s, Pressure vessels.
