The synthesis of tin-coated carbon fibers (CFs) by electroless deposition method in aqueous solution was studied. Sodium hypophosphite was used as a reducing reagent. The composites were characterized by Xray diffraction, energy-dispersive X-ray spectroscopy and scanning electron microscopy techniques. The experiment results showed that the car fiber surfaces can be fully deposited by tin layers and a continuous tin coating on carbon fiber was obtained by electroless deposition. These tin@carbon fiber composites can be used in some possible applications such as electrode materials, fiber-matrix composites, and so on
