The technique of using carbon polymer fibers to strengthen and rehabilitate structural beams considered one of the modern techniques that have proven its effectiveness in various civil engineering projects. From this point of view, this review came to clarify the practical benefit of using this technology to inform researchers and workers in the construction sector about it and to provide modern sources for those wishing to conduct More researches in the field of strengthening and rehabilitating concrete, iron and composite structural beams and highlighting the studies that dealt with flexural, shear and torsion resistance of beams and reinforced with carbon polymer fibers externally or internally . 

The use of Carbon Fiber Reinforced Polymers CFRP in strengthening and rehabilitating structural members is one of the modern techniques which proved to be effective in different civil engineering applications. This review aims to provide the researchers and construction specialists with a detailed description on the practical application of External or Internal  Carbon Fiber Reinforced Polymers in strengthening and rehabilitating concrete, steel, and composite members in flexure and shear.
