Abstract
A filament winding assembly includes a rotating mandrel coupled to a shaft that rotates the rotating mandrel. The rotating mandrel includes a first perforated sleeve that defines holes and includes a winding surface. The rotating mandrel also includes a second perforated sleeve disposed inside the first perforated sleeve. The second perforated sleeve defines an interior volume and holes configured to form fluid pathways with the holes of the first perforated sleeve. The fluid pathways extend from the interior volume to the winding surface of the first perforated sleeve. The filament winding assembly includes a filament that is wound, under tension, around the winding surface of the first perforated sleeve. The filament winding assembly also includes a fluid source fluidically coupled to the interior volume of the second perforated sleeve. The fluid source exhausts fluid, through the fluid pathways, from the wound filament to reduce manufacturing defects of the wound filament.
