The performance of aircraft anti-icing fluids reduces unusually on aviation composites. It is unclear whether this is due to low substrate thermal conductivity or hydrophobicity. Therefore, we considered experimentally the performance of Newtonian and non-Newtonian aircraft anti-icing fluids on substrates with thermal conductivities from 0.17 to 252 W/m∙K. It was found that the decrease of substrate thermal conductivity promotes the freezing of Newtonian and low viscous Non-Newtonian fluids compared to the thicker Non-Newtonian one. The thermal conductivity effect can be explained by the competition of two heat transfer processes: heat accumulation and the transfer of latent heat. Thus, Newtonian and low viscous Non-Newtonian aircraft anti-icing fluids must be defined on aviation composites together with substrate thermal conductivity, wettability, and roughness.

飞机防冰液的性能在航空复合材料上异常降低。尚不清楚这是否是由于低基板热导率或疏水性。因此，我们通过实验考虑了牛顿和非牛顿飞机防冰液在导热率为 0.17 至 252 W/m∙K 的基材上的性能。研究发现，与较厚的非牛顿流体相比，基质热导率的降低促进了牛顿流体和低粘度非牛顿流体的冻结。热传导效应可以通过两种传热过程的竞争来解释：热量的积累和潜热的传递。因此，必须在航空复合材料上定义牛顿和低粘度非牛顿飞机防冰液以及基材导热性、润湿性、
