The effect of kind and thickness of the metal layer and thickness of the CFRP (Carbon Fiber Reinforced Plastics) layer on the thermal deformation characteristic of active laminate was examined experimentally and compared with theoretical value obtained from three-layered beam model. Various types of the laminate made of the metal layer, that is, aluminum, 2024 aluminum alloy, SUS304 stainless steel, zinc and titanium, a unidirectional CFRP prepreg and a unidirectional KFRP (Kevlar Fiber Reinforced Plastics) prepreg to insulate them were fabricated by hot-pressing at 393 K. The main results are as follows: (1) The experimental values of the curvature of the active laminate using mono-layers of CFRP and KFRP prepregs correspond with theoretical values. (2) Actuation of active laminate was examined and it was theoretically found that aluminum and magnesium can realize high level of actuation, and it was experimentally found that aluminum and 2024 aluminum alloy can realize high level and unidirectional actuation, and SUS304 stainless steel can realize similar actuation, but causes snap-through around 393 K. (3) The effect of CFRP thickness on the curvature of active laminate at 313 K was experimentally examined and it corresponded well with theoretical values.
