Generation of filament winding path for tee pipe

Filament winding is an efficient method to produce fiber-reinforced composite product. However, it is difficult to automatically manufacture tee pipe by filament winding because of complex shape. In this paper, a key point based method is proposed to generate winding path for tee pipe. The key points are connected by two non-geodesic lines with different slippage tendency to ensure the stability of filament. The motion path of deposition head is generated by calculating the intersection between filament and envelope. For the problem of collision and unexpected intersection between filament and pipe occurred in winding, post processing method is developed to adapt motion path by inserting points on the discontinuous path.
