Multifunctional materials and structures are increasingly investigated for integrated design, such as embedding heating elements for ice protection. However, the thermal mismatch between different plies and materials will lead to property degradation after thermal cycling. CNT/GFRP/CFRP composites with different thermal cycles between -55 and + 80 °C were studied in this work, to simulate the anti-icing/de-icing service conditions. The interlaminar shear strength decreased by 1.8%, 4.5% and 5.9% respectively after 100, 500 and 1000 thermal cycles, and the experimental results fitted very well with the Bulmanis et al. model, which could be used to predict the strength degradation of the composites during thermal fatigue.

摘要

Multifunctional materials and structures are increasingly investigated for integrated design, such as embedding heating elements for ice protection. However, the thermal mismatch between different plies and materials will lead to property degradation after thermal cycling. CNT/GFRP/CFRP composites with different thermal cycles between -55 and + 80 °C were studied in this work, to simulate the anti-icing/de-icing service conditions. The interlaminar shear strength decreased by 1.8%, 4.5% and 5.9% respectively after 100, 500 and 1000 thermal cycles, and the experimental results fitted very well with the Bulmanis et al. model, which could be used to predict the strength degradation of the composites during thermal fatigue.
