This paper describes fabrication of higher performance CFRP/aluminum laminate actuators by investigating various factors such as mechanical properties of aluminum plate. bonding strength between FRP prepreg and aluminum plate. and glass transition temperature of the matrix resin. According to the experimental results. the following conclusions were obtained. (1) Curvature of the actuator increases with increasing proportional elastic limit of the aluminum plate in the experimental range. (2) In order to maintain high bonding strength between the aluminum plate and the FRP prepreg up to higher temperature range. roughness must be given on the aluminum plate or the matrix resin must be replaced with higher glass transition temperature one. (3) The curvature at room temperature of the higher cure temperature type actuator was 1.5 times of that lower temperature type one. They decreased linearly with increasing temperature and became zero at each curing temperature. (4) The force generated by an actuator made of higher temperature (453K) cure type epoxy linearly increases with increasing temperature up to higher temperature range compared with that of lower temperature (393K) one and the maximum force reaches about 1.5 times that of lower temperature one.
