ABSTRACT:
A process of forming a tubular member includes rotating a tubular form about a central axis. The form is provided with an interior coating of time-setting, liquid material. A number of lengths or strips of roving, preferably of fiber glass, are introduced serially into the rotating tubular form in a direction substantially chordally of the tubular form so that each roving strip tends to be embedded approximately circumferentially by centrifugal force into the liquid material. The roving strips are approximately as long as the diameter of the tubular form and in effect make a helix. The material hardens with the roving embedded therein. The hardened material and roving are then removed as a tubular member from the stationary form. The product of the invention is a member of tubular shape comprised of a helix formed of substantially circumferentially extending lengths of fiber glass roving, each length being approximately the diameter of the tube, all embedded in a solid matrix of time-setting material.
