Abstract
Abstract. Recently, Università Politecnica delle Marche and COMEC Innovative srl are involved in the research project “Smart Tow Winding” funded by MIUR (Ministry of Education, University and Research), concerning the development of an innovative process for the realization of a pressure vessel through Filament Winding (FW) technology. In this context, a design procedure for type IV composite pressure vessel is proposed. To design the component, the dedicated simulation software CADWIND was used to virtually generate the pressure vessel through the definition of the desired geometry, the type of prepreg, the number of layers and the bandwidth. The generated file was imported in the FEM simulation software Siemens NX with the aim of evaluating the structural resistance under an internal pressure of 70 MPa. Different external configurations of mandrels and stratification were tested in order to optimize the geometry of the vessel and the resistance to weight ratio. A high performance and low weight vessel configuration was finally identified.
