A NEW ROBOTIZED FILAMENT WINDING CELL TOMANUFACTURE COMPLEX SHAPE PARTS

摘要

This work shows a robotized filament winding cell that allows to produce composite parts,characterised by high functional performances, by controlling process parameters: tension fibre,winding trajectory and deposition speed. In order to optimise the winding process, it is necessary toattain the following objects: I) to control and plan the winding trajectories in order to amplify thetypology and the complexity of the parts to realize; ii) to maximize the deposition speed, in order toreduce manufacturing times; iii) to control the winding tension, in order to improve the mechanicalproperties of the parts. With regard to these objects a new cell that consists of an anthropomorphicrobot, a fixed support and a unique device including a fiber feed spool, a fiber tensioner and adeposition system, has been realized. The new cell has proved to give better results in all processconditions and to satisfy the acceptable limits established by the well-known aeronautic company.The use of a cell with such characteristics represents an important step for the industrial developmentof the filament winding technology applied to the manufacturing of complex shapes.
