关 键 词：Shape Memory Polymer Hybrid Laminates Damping Characteristic Temperature Dependency
摘 要：正Carbon fiber reinforced plastics （FRP） are often used for structural components where the strength under repeated load is required. But the vibration reduction for FRP materials is difficult to be realized. In this paper, in order to improve damping characteristics of FRP materials, the innovative laminates with the shape memory polymer that has good damping characteristic and carbon fiber （SMP/CFRP） hybrid laminates that can be heated in internal layer were developed. The damping characteristic was investigated by the mechanical impedance method and dynamic mechanical analysis. The influence of lamination position and contents of SMP in hybrid laminates on damping characteristic was discussed. As a result, it was shown that damping property has strong dependability on electric current and temperature factors. It was found that the developed hybrid laminates had excellent damping performance.
