中文摘要：

针对风力发电叶片在多风沙环境下的固体粒子冲蚀磨损行为，研究了风力发电叶片专用环氧树脂（EPIKOTE“RIM135、EPIKuRE RIMH137）、传统玻纤增强环氧复合材料和新型碳纳米纤维纸一玻纤／环氧复合材料的固体粒子冲蚀磨损行为，并测试了不同材料的玻璃化转变温度，进而对比分析了其对冲蚀磨损的影响；针对风力发电叶片在寒冷环境下表面容易结冰的现象，研究了上述三种材料表面的疏水性能，并测试了它们对水的接触角大小。结果表明：碳纳米纤维纸一玻纤／环氧复合材料具有良好的界面结合，且碳纳米纤维纸的引入提高了碳纳米纤维纸一玻纤／环氧复合材料的玻璃化转变温度（从55℃提高到63℃），从而改善了其耐固体粒子冲蚀磨损性能；同时，碳纳米纤维纸的加入改善了碳纳米纤维纸一玻纤／环氧复合材料的表面疏水性能（接触角从104°提高到131°）。

英文摘要：

According to wind turbine blade worked in sandy environment, high winds can carry abrasive particles disrupting the blade and reducing its aerodynamic efficiency, the behaviors of sand erosion were investigated. In this paper, three different samples： the pure epoxy （EPIKOTETM RIM 135, EPIKURETM RIM H 137 especially for wind turbine blade）, the conventional glass fiber reinforced composite and the carbon nano-fiber paper - glass fiber/ epoxy composite were compared in terms of wear loss, surface profile, glass transition temperature and water contact angle. For the erosion testing, the mass loss of the traditional composite is larger than that of pure epoxy resin, and that of carbon nano- fiber paper - glass fiber/epoxy composite. Compared with traditional composite, carbon nano-fiber paper- glass fiber/epoxy composite shows a higher glass transition temperature （from 55 ~C increased to 63 ＊C ） and a larger contact angle （from 104~ increased to 131~, more hydrophobic）, which can improve the heat-resistance performance and the anti-ice properties. This novel carbon nano-fiber paper- glass fiber/epoxy composite has a great potential as a coating materials for wind turbine blade, providing erosion resistance, preventing ice-buildup, and reducing the energy loss.
