Winding Trajectory and Winding Time in Robotized Filament Winding of Asymmetric Shape Parts

Abstract

Robotized filament winding is a technology to deposit a roving on a die according to a planned robot trajectory and to polymerize the wound part in a furnace for thermoset resin matrix. In this way, it is possible to wind asymmetric or complex parts. The winding trajectory is a critical aspect of the robotized filament winding process, since the mechanical performances and the winding time of the manufactured composite part change according to winding trajectory geometry. The present work discusses original criteria for the determination of a proper winding system trajectory and its influence on the winding time. This work studies the influence of the geometric parameters, that characterize the trajectory covered by the deposition system to wind the roving on the die, on winding time. The obtained results may help to identify the values of the geometric parameters that minimize the winding time and, at the same time, that keep constant the winding tension in order to assure an acceptable quality of composite parts. This work represents the first step to optimize the planning of the winding trajectory.
