Recently, composite materials have widely become available to engineers. This paper briefly explains the applications of these materials and shows how these materials can be used to repair structures with damages such as crack, notch, etc. Before the fatigue test, notched and repaired specimens with thin laminate composite are prepared. Also, test apparatus is designed to perform four point fatigue test of specimens. From the experimental result, it was found that present repair technique could be used to enhance the life of damaged structures.
