This paper describes the effect of kind and thickness of the metal layer on the actuator characteristic of active laminate was examined experimentally and compared with theoretical value obtained from three-layered beam model. Various types of the laminates made of the metal layer, that is, aluminum, 2024 aluminum alloy, SUS304 stainless steel, zinc and titanium, a unidirectional CFRP (Carbon Fiber Reinforced Plastics) prepreg and a unidirectional KFRP (Kevlar Fiber Reinforced Plastics) prepreg to insulate them were fabricated by hot-pressing at 393K. The main results are as follows: (1) The experimental values of the curvature of active laminate using mono-layers of CFRP and KFRP prepregs corresponded with theoretical value. (2) Actuation of active laminate was examined and it was theoretically found that aluminum can realize high level of actuation, and it was experimentally found that aluminum and 2024 aluminum alloy could realize high level and unidirectional actuation, and SUS304 stainless steel could realize similar actuation, but caused snap-through around 393K.
