Abstract
The disclosure provides for a method including: a) forming a layered tubular member (12) by placing one or more outer layers (16) about an inner layer (14) and joining at one or more seams (56) along a length of the layered tubular member, wherein the one or more outer layers include a first resin impregnated therein; b) applying the first resin or a second resin at the one or more seams; c) creating one or more fillets (58) along the one or more seams with the first resin, the second resin, or an adhesive; and d) curing the first resin, the second resin, and the adhesive so that the layered tubular member, the first resin, the second resin, and the adhesive form a composite structure having a tubular shape.
