This paper describes development of high performance CFRP (Carbon Fiber Reinforced Plastics) metal active laminates which can work as actuating panels only bending in the fiber direction driven by electric resistance heating of the carbon fiber. The development was undertaken mainly by investigating the effect of kind and thickness of the metal layer on their deformation characteristics. Various types of the active laminates were made by hot-pressing of a metal layer as a high CTE (Coefficient of Thermal Expansion) material, a unidirectional CFRP prepreg as a low CTE and electric resistance heating material, and a unidirectional KFRP (Kevlar Fiber Reinforced Plastics) prepreg as a low CTE and insulating material. Performance of the active laminate under constant thicknesses of the CFRP and KFRP prepregs kept at mono-layer were examined and it was found that the pure aluminum and the magnesium alloy realized high level and unidirectional actuations, and the stainless steel realized a actuation a little less than these levels and unidirectional
