Abstract: A structural lining system and a method of applying the system to the interior surface of a pipe. First, a layer of adhesive is sprayed onto the interior surface of a previously cleaned pipe. Next, strips of previously coiled unidirectional carbon fiber material are allowed to uncoil within the pipe so that side edges of the strips abut the side edges of adjacent strips and the junction where the ends of each strip come together are staggered around the pipe so that the junction for adjacent strips do not align longitudinally. If ends of the strips overlap, additional adhesive is applied between the overlapping portions. A final epoxy coating is sprayed over the strips, forming an internal liner for the pipe.
