先采用真空袋压法制备含CaCO3/环氧树脂表面功能层的玻璃纤维增强环氧树脂复合材料,再通过化学刻蚀与表面修饰,在玻璃纤维增强环氧树脂复合材料上制备出超疏水表面。采用扫描电镜和动/静态接触角分析仪,表征表面的形貌和疏水性,结果表明,在复合材料表面构建了具有微-纳米尺度二元粗糙结构;采用1%（质量分数）的硬脂酸修饰后,其表面与水的接触角最高达160.03°;制备的超疏水表面结构在室温环境下具有长期的稳定性。
By vacuum/pressuer bag mouding techniques,a glass fibers reinforced epoxy composite materials which has the functional layer of CaCO3 and epoxy resin were prepared.A method to form superhydrophobic surface on the glass reinforced epoxy composite materials by chemical etching and surface modifing technique was investigated.The morphologies and superhydrophobicity were analyzed by scanning electron microscopy（SEM） and water contact angle measurement.The results showed that the micro/nano-binary porous structure was formed on surface of the glass reinforced epoxy composite materials and the water contact angle value of the surface was up to 160.03°.In addition,stored in an ambient environment,the as-prepared superhydrophobic surface has essentially stability.
