Abstract:
A structural lining system for lining an interior surface of a hollow cylindrical structure comprising:a hollow structure having an interior surface, an adhesive layer applied to said interior surface, and strips of flat stock of factory manufactured and cured unidirectional carbon fiber material approximately 0.5-1.4 mm thick and approximately 2-12 inches wide, each said strip secured circumpherentially to the interior surface of the hollow structure via the adhesive layer, side edges of each strip abutting side edges of adjacent strips, and opposite ends of each of the strips joined at a junction to form a single layer of circumpherentially disposed hoops of strips lining the interior surface of the hollow structures, wherein the tensile strength of the unidirectional carbon fiber material is at least 275,000 psi.
