In this study, erosion wear tests in composites materials (carbon fiber and fiberglass) were performed in order to understand their behavior for blades of wind turbine applications. The erosion tests were also made in coated composites materials with a polyester resin (gel coat), to compare the wear erosion resistance with uncoated materials. The experimental tests were carried out according to some parameters to the ASTM G76 standard. The specimens had a rectangular shape with dimensions of 25 × 18 mm and a thickness of 4 mm. The erosive particle used was obtained from sea sand. High impact angles were used, 75°, 85°, and 90° and the velocity particle was 12 m/s. The duration of each test was 6 min, removing the specimens every 2 min to measure the amount of mass loss. In order to identify the wear mechanisms, scanning electron microscopy was used. The results showed that fiberglass specimens had a higher mass loss at 90° impact angle. The best erosive wear performance was obtained in the uncoated carbon fiber specimens at 85° impact angle.

风力涡轮机应用聚合物复合材料的固体颗粒侵蚀磨损研究
在这项研究中，对复合材料（碳纤维和玻璃纤维）进行了磨损试验，以了解其在风力涡轮机叶片中的性能。还对带有聚酯树脂（凝胶涂层）的复合材料涂层材料进行了腐蚀测试，以比较未涂覆材料的耐磨蚀性。根据ASTM G76标准的某些参数进行了实验测试。样品呈矩形，尺寸为25×18 mm，厚度为4 mm。所使用的侵蚀性颗粒是从海砂中获得的。使用了75°，85°和90°的高冲击角，速度粒子为12 m / s。每次测试的持续时间为6分钟，每2分钟取出一次样品以测量质量损失的量。为了确定磨损机理，使用扫描电子显微镜。结果表明，玻璃纤维试样在90°冲击角下具有较高的质量损失。在85°冲击角下，未涂覆的碳纤维样品获得了最佳的腐蚀磨损性能。
