    摘要:

    针对无人机复合材料蒙皮表面结冰问题，设计了一种超疏水-电加热膜-复合材料一体化结构，结合超疏水制备技术与嵌入式电加热膜一体化成形工艺制备多层复合结构。其中，环氧树脂基的超疏水涂层具有优异的疏水性能，水滴延迟结冰时间增加18倍，提高防冰效果；加热膜与复合材料的一体化结构，增强热传导方向，提高电热转化效率，从而提升除冰效果。通过自主搭建试验台，对超疏水-电加热膜-复合材料一体化构型进行防除冰实验。实验结果表明，超疏水-电加热膜-复合材料一体化方法在达到防除冰效果的同时，除冰节能35%左右，具有高效防除冰和降低能耗的可行性。

    Abstract:

    In order to solve the problem of UAV composite surface icing， an integrated structure of superhydrophobic coating， electrothermal film and composite surface is designed and prepared. The multilayer integrated structure consists of the superhydrophobic coating preparation method and the embedded electrothermal film process. The superhydrophobic coating based on epoxy resin has excellent hydrophobicity， which increases 18 times longer than untreated one for delayed icing time of water droplets， and thus the anti-icing effect is improved. The integrated structure of heating film and composite surface enhances the directivity of heat conduction， which improves the efficiency of electrothermal conversion， and thus the de-icing effect also is improved. The de-icing and anti-icing tests of integrated structure are verified by self-designed test platforms. The experimental results show that the energy consumption is cut by about 35% by integrated structure of superhydrophobic coating， electrothermal film and composite surface. The integrated structure is feasible to achieve the anti/de-icing effect and reduce energy consumption.
