摘要

When composite parts are manufactured by robotized filament winding technology, winding tension is a very important parameter to be controlled since it influences directly the defects and the mechanical property of these parts. The present work aims to study the influence of the main winding parameters on tension during the manufacturing of full section composite parts. In particular, the focus of this work is to determine both the geometric parameters characterizing the winding trajectory and the winding speed that allows to keep the winding tension near to the nominal value that has been planned to have good composite parts. The geometric parameters of the winding trajectory are the number of points used to approximate the winding trajectory, the trajectory angle and the distance of the deposition system from the winding die in order to avoid collisions (called safety distance). The conclusions developed in this work may be used to understand the change in tension average value of winding typology.
