DEVICE AND METHOD FOR THE FIBER DEVELOPMENT OF LONG TUBES AND LONG TUBES MADE ACCORDING TO THE METHOD

摘要

The invention relates to a device and a method for the filament-winding of long tubes, comprising the step (4) of unwinding filaments (12), the step (1) of impregnating the filaments with a resin (13), characterised in that it comprises the step of positioning a mandrel (14) between the ends (34, 35) of a lathe (26), the step of resting the mandrel on a rotating bearing system (36) with rollers (36), in which the rollers are arranged to apply a controlled pressure on the part being wound as the diameter of said part increases together with the deposition of fibre filaments, the step of rotating the lathe and the step (2) of winding the impregnated filaments on the mandrel, and 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). Application for tubes.
