This paper describes enhancement of functionality in the active laminate by introducing hollow channels. 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. Firstly, the effects of formation of the hollow channels on the time for air cooling and forced cooling, that is, air-flow cooling and water-flow cooling, were investigated. The cooling rate of the active laminate having one hollow channel was improved with increasing its volume fraction up to 0.9, and it was greatly improved by water-flow cooling. Secondly, the effect of humidity on the shape of the active laminate was investigated. The curvature of the active laminate is increased by moisture absorption and this increase is enhanced by formation of the hollow channels.
