Abstract

This paper describes the effect of humidity on the shape of the active laminate. The active laminate was made by hot-pressing of an aluminum plate as a high CTE material, a unidirectional CFRP prepreg as a low CTE material and an electric resistance heater, a unidirectional GFRP prepreg as an insulator between them and copper foils as electrodes. The hollow channels were formed in the GFRP layer. In this study, it was found that the curvature of the active laminate is increased by moisture absorption and this increase is enhanced by formation of the hollow channels in the GFRP layer.
