A method of strengthen concrete structures with hybrid fiber sheet(composed of carbon fiber and glass fiber) was proposed. Yield load, limit load, middle deflection of reinforced concrete beam and load-strain curves of reinforcing steel bar and reinforced materials, destroy configuration and strain distribution of section along beam depth were measured through experiments. It is shown that the average strain distribution of the reinforced beam is according with flat section assumption. Using of reinforced materials(carbon fiber, hybrid fiber) is a feasible way to improve the bend bearing capacity of the concrete component. The bend bearing capacity of the concrete component is improved as the amount of added reinforced materials increasing and it is affected by the hybrid mode and compound ratio. The bending resistance, extensibility and economical efficiency of the inner hybrid fiber reinforcing are better than the sole fiber or inter hybrid fiber reinforcing.
