Abstract
A rigid plastic composite tube includes a first sleeve of helically braided metallic ribbons, a second sleeve engaged with the first sleeve either on the inside or outside thereof, the second sleeve being of helically braided fibrous strands, said sleeves being embedded in solid plastic material to form a unitary composite tubular structure. The method of this invention for fabricating such plastic composite tubes comprises the steps of braiding metallic ribbons and fibrous strands about an elongated form, conforming the ribbons to the shape of said form by tensioning the strands during the braiding thereof, impregnating the composite sleeve with liquid hardenable plastic, and then hardening the plastic thereby providing a solidified plastic composite sleeve.
