Abstract

Fiber reinforced polymer (FRP) composites are increasingly being used for the renewal of civil infrastructure since they provide enhanced properties, potentially long-term durability, and fabrication/construction options often not possible with conventional materials. Initially used extensively for seismic retrofit, these materials are now being used in a variety of forms for repair and strengthening of beams, girders, and slabs, and for the development of new bridge, building, and industrial structural systems. This paper provides an overview of some applications in the area of repair and strengthening, emphasizing the importance of, and the effects of, choice of materials and processes. Aspects relating to durability, the current state of knowledge in this area, and test standards are also discussed. Opportunities and challenges pertaining to the development of new materials and processes designed specifically for this sector of the FRP industry are also discussed.
