Abstract
A reinforced pipe including a pipe made of a metal which is subject to ductile fracture propagation and a reinforcing wrapping extending around and in contact with the pipe for preventing the ductile fracture propagation. The reinforcing wrapping comprises a plurality of lightweight, continuous, unidirectional, high strength, non-corrodible, electrically nonconductive fibers extending helically around the pipe under a limited tension which is less than the tension which would cause the fibers to break during wrapping, the fibers being encapsulated in a curable viscous matrix to define a continuous composite material.
