Fibre reinforcement polymer (FRP) is a repair material of fibres of high strength, high stiffness embedded in a polymer matrix with tensile strength of 1000-5000 MPa in different varieties. The FRP matrix consists of a polymer or resin used as binder for the reinforcing fibres. The use of FRP has been increased because of their high strength to weight ratio, low longitudinal and transverse coefficient of thermal expansion, low sensitivity to fatigue loads and adequate resistant in aggressive environment. A lot of research reported the different properties of FRP exposed to different cracks and environmental conditions. This paper presents a review of different FRP types, their properties and their probable failures in various conditions by means of experimental and numerical research results. © IDOSI Publications, 2013.
