| Research Abstract |
The present study generated a new function of carbon fiber reinforced laminated materials, known as advanced composite materials with high specific stiffness and strength. New structures of composite materials with curvilinear reinforcement fibers and variable-thicknesses were proposed in this study, and this structure realized local anisotropy in different positions of structures. Optimum placements of local anisotropy induced by optimum curvilinear fiber shape and distributed thickness resulted in controlling shapes of vibration mode arbitrary. The technique was applied to design optimum smart composite structures to enhance the performances of vibration suppression. From above, it is concluded that the present technique enables effective usage or suppression of vibration by considering the shape of vibration mode.
