复合材料层合结构在防覆冰/除冰系统中的应用

摘要/Abstract

摘要： 设计了一种基于复合材料层合结构的新型防覆冰/除冰系统。此多功能复合层合结构由铜基超疏水材料、非对称正交铺设的双稳态可变形结构和聚酰亚胺加热膜构成。铜基超疏水材料起到延迟水滴结冰、减少表面覆冰和降低冰层与接触面之间黏附力的作用；聚酰亚胺加热膜驱动双稳态结构发生稳态突变时，产生的热量会快速融化冰层；双稳态结构形态突变时会产生机械振动，从而形成一套新型电热-机械耦合防覆冰/除冰机制。通过测试，该系统表面水接触角可达155°，具有良好的超疏水特性、可变形性、耐高低温交变性和紫外线耐性等特性。

Abstract: A new anti-icing/de-icing system was designed based on composite layups. The multi-functional composite structures consisted of copper-based superhydrophobic materials, asymmetric cross-ply of bi-stable structures and polyimide heating films. Copper-based superhydrophobic materials played a role in delaying water droplets of icing, reducing icing capacity and the adhesion between ice and surface. When the bi-stable structures were driven using heating method by polyimide films, the heat could also melt the ice on the surface; the snap-through processes of bi-stable could generate mechanical vibration, which formed a thermo-mechanical coupling anti-icing and de-icing mechanism. The surface of system has good superhydrophobic characteristics with the water contact angle reaching 155°. Besides, the system has good deformability, resistance to high and low temperature alternating and ultraviolet(UV) resistance.

Key words: composite laminated structure, anti-icing/de-icing system, bi-stable structure, copper-based superhydrophobic material
