This paper presents a new filament winding process for multi-polar holes componet. Some kinds of filament winding components work as connecting piece which has many holes. Traditionally, the hole is usually machined after the fabrication of composite components. This will lead to the fibers around the holes are cut off. In addition, it would also increase the risk of composites delamination and crack around the area of the holes. In order to eliminate these defects, the multi-polar holes filament winding process was proposed. The winding trajectories of a sphere with two non-axial polar holes were designed and tested. Then, by calculating the area of fiber sparse zone and fiber volume fraction of this winding component, it was found that the radiuses of polar holes can significantly influence the area of fiber sparse zone and fiber volume fraction.
