The antisymmetric laminate (Al/KFRP/CFRP) consisted of aluminum, Kevlar reinforced fiber, and carbon fiber reinforced plastics can design its shape through curing at high-temperature. The shape of the laminate can be predicted by the Rayleigh Ritz potential energy minimization principle. By using these characteristics, it is possible to control the shapes by controlling joule-heat generated from electric power, which is controlled through the signal of a temperature sensor buried in the laminate. The Al/CFRP antisymmetric laminate is called the smart material. This study aims to develop a method for rotation control of smart material blades of small wind power generators. Two methods of the rotation control, i.e., decreasing-lift method and inducing-stall method, were experimentally carried out. The experiments showed that the inducing-stall method was more efficient than the decreasing-lift method.
