abstract Wet filament winding is a well-established process to manufacture fibre reinforced polymer (FRP) pressurised vessels. However, due to the large number of process parameters and their interaction, it is difficult to achieve the best component properties from the material system used. For this reason, this article presents an optimisation sequence for setting the individual process parameters, taking into account and prioritising the interactions that occur in each case. The methods employed to optimise the individual process parameters are presented in detail and corresponding production tests were carried out with an exemplary material system. In the course of evaluating the component quality achieved by varying the process parameters using NOL ring tests and analysing micrographs of test specimens, the corresponding optimum process settings for the material system were defined and the achievable component quality was documented.
