The paper presents essential stages of designing and manufacturing of composite tanks. Design of composite vessels makes use of computer-aided analytical methods. However, in contrast to metal vessels there is no unique commonly accepted analytical method allowing determination of tank strength because of large error of these calculations. Therefore, the unique way to accept a construction of composite tank is to pass the homologation tests related to future applications, which is accompanied by much prototyping work and rework. Every discrepancy with standards must be verified many times resulting in large cost and time consumption of performed homologation tests (lasting up to two years). In this study, designing has been based on wind choice referring to the table method elaborated in the Institute of Materials Science and Applied Mechanics of Wroclaw University of Technology, PL. Manufacturing makes use of winding treated as output data from computer-aided design (CAD). Testing methods of prototypes as well as evaluation and return to design stage are discussed. Sufficient number of run loops enables high quality of product. In this paper, remarks are presented related to lowering of manufacturing costs and increase of effectiveness of winding process. Discussed problems result from research carried out by the Institute of Materials Science and Applied Mechanics and devoted to implemented technology of manufacturing of composite tanks. In winding method, time necessary to arrange fibres is very long compared with low-pressure composite tanks made with the help of form pressing. To diminish manufacturing time, machines with multiple spindles are applied as well as beams of fibres like bands. Moreover, winding may be started from many points simultaneously. Effective impregnants and chemical processes become additional elements effecting final product. This may substantially reduce costs of manufacturing, but composite tanks are still expensive.
