Although fiber reinforced plastics (FRP) are often used for structural components and functional materials, the vibration reduction for FRP materials is still difficult. The hybrid construction of FRP is well known as more effective for the improvement of this property. In this paper, in order to improve damping characteristics of FRP materials, carbon fabric reinforced shape memory polymer (SMP/CFRP) hybrid laminates are developed. The bending and damping property is investigated by the three-point bending test and mechanical impedance method. The influence of lamination position and contents of SMP in hybrid laminates on mechanical property is discussed. The theoretical formula for bending modulus and bending strength was proposed, and the validity was confirmed by experiment. The results show that the developed hybrid laminates has high bending modulus and excellent damping properties.
