Cost-effective glass-reinforced thermoplastic matrix towpregs produced by a powder coatingline were used to manufacture composite pipes by filament winding. A conventional 6 axesfilament-winding equipment was adapted for processing such structures. The influence of thefilament winding speed and mandrel temperature on the composite final properties wasstudied in the present work. An optimized processing window was established by comparingthe composite theoretical expected mechanical properties with the experimentally obtainedones. The final properties determined on the produced pipes and structures and thetechnological changes introduced to the conventional filament-winding equipment will bepresented and discussed. Besides the processing description and conditions, it will bepresented the relationship between processing conditions and mechanical properties.
