Present study focuses on the carbon fiber sizing and their effect on overall mechanical properties of composites. Fiber sizing are one of the most important component in the manufacturing of composites. As the sizing are so much of importance in the manufacturing and development of composites which governs mechanical properties such as strength and stiffness. In this review some of the important articles are referred from the widely dispersed literature. This review covers the sizing effect, adhesion between fiber and matrix and characterization of composites
