    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.

    Abstract: A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; wherein the first pipe and the second pipe are made from a reinforced thermosetting resin (RTR), and a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe, wherein a thermoplastic material is disposed between an exterior of the first pipe and an interior of the coupler. A thermoplastic material is disposed between an exterior of the second pipe and the interior of the coupler. Upon application of induction heating to the coupler, the heat between the first pipe, the second pipe, and the coupler is sufficient to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler.
