    Abstract: A method of forming a tube with an inner wall having a high-wear resistance and a low coefficient of friction comprising: deaerating an uncured thermosetting resin, coating glass filaments with the resin, and winding the glass filaments about a rotating mandrel in a band at a pitch no greater than the bandwidth. A first layer of wound glass filaments is formed in a single axial pass along the mandrel, and this first layer is helically overwound with subsequent layers. The resin coating the wound glass filaments is thereafter cured and the resulting tube is removed from the mandrel.
