中文摘要:
      飞机积冰一直是威胁飞机安全的重要因素之一,而传统飞机除冰方式在面对未来全电飞机和智能飞行的改变中显得力不从心。本文提出一种基于Ni、CNT和LIT-PDMS的疏冰-涡流热效应一体化的新型复合材料,既具有疏水性可预防结冰的特性,又可利用涡流热效应进行非接触式除冰。Ni-CNT/LIT-PDMS复合材料静态接触角约为106.5°,为疏水性材料,能有效水珠阻止在飞机表面聚集进而结冰;在感应加热装置输入电压为30V时,其发热最高平衡温度约为119℃,且能进行多次加热且具有良好的热稳定性,完全融化20g的冰层只需要232 s;在ε=0.001的30次循环拉伸中,其内部导电网络具有良好的稳定性和回弹性。Ni-CNT/LIT-PDMS复合材料可以完成飞机除冰工作,保障飞行安全。

英文摘要:
      Aircraft ice accumulation has always been one of the important factors that threaten the safety of aircraft. However, the traditional aircraft de-icing method is unable to cope with the changes of all-electric aircraft and intelligent flight in the future. A new composite material based on Ni, CNT and LIT-PDMS is proposed in this paper, which can make use of eddy current thermal effect for non-contact de-icing, and maintain its reliability in the complex working environment of aircraft. The ni-cnt/lit-pdms composite has a static contact Angle of about 106.5°, which is hydrophobic and can effectively prevent water droplets from accumulating on the surface of the aircraft and thus freezing; When the input voltage of the induction heating device is 30V, the maximum equilibrium temperature of its heating is about 119℃, and it can be heated several times with good thermal stability, only need 232 s to completely melt 20g of ice; the internal conductive network of composites has good stability and resilience after theε=0.001 30 times tension. Ni-CNT/LIT-PDMS composites material can complete the aircraft de-icing work, to ensure flight safety.
