1339 Effect of Hollow Channels Formed in CFRP/A1 Active Laminate on Its Actuation and Output Force
Details
This paper describes the fabrication and evaluation of the active laminates having hollow channels to develop new functions such as cooling and healing. 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 thermal deformations and output forces of the active laminates having one hollow channel decreases with increasing the volume fraction of the hollow channel up to 0.9. However, they were improved by increasing the number of the hollow channels.
