摘要/Abstract

摘要： 模拟风电叶片蒙皮铺层结构,采用真空辅助灌注成型工艺制备了含高分子电热膜的夹层结构玻璃钢样板,研究了在不同环境温度和功率密度下的通电加热效果,通过实验数据拟合出了灌注后的高分子电热膜具备防除冰能力所需的最小功率密度与所处环境温度的关系式,并研究了低温环境中不同功率密度下的除冰性能。结果表明,在-11~-13℃环境中且表面覆冰厚度为1cm的情况下,在200~600W/m²功率密度范围内的除冰时间可控制在1~3h。

Abstract: Glass-fiber-reinforced epoxy resin plates containing sandwich core structure and polymer electric heating film were prepared via vacuum assisted infusion molding process by simulating the skin lay-up structure of wind turbine blade. The heating effects of the plates under different environment temperature and power density were investigated. The relationship between the minimum power density of polymer electric heating film required by de-icing and anti-icing and corresponding environment temperature was fitted out by experimental data. The de-icing performance of the plate containing polymer electric heating film in low temperature environment under different power density was also studied. The results show that, in 200~600W/m² power density range, the de-icing time of the plate with 1cm ice thickness in the -11~-13℃ environment could be controlled in 1~3h.

Key words: wind turbine blade, glass fiber reinforced plastic, anti-icing, de-icing, polymer electric heating film
