More Information
Summary:The invention relates to a filament winding method that comprises the step (4) of unwinding filaments (12), the step (1) of impregnating the filaments with a resin, and the step (2) of winding, characterised in that it comprises the step (3) of adapting the resin viscosity for the impregnation step (1), in that the impregnation step is carried out on the filaments after unwinding using a non-polymerized resin fluidised during the viscosity adaptation step (3), and in that it comprises the step (5) of increasing the resin viscosity between the impregnation step (1) and the winding step (2).
