Basalt/epoxy composite pipes in a [±55] winding configuration were produced on CNC filament winding machines (10 N fiber tension and ~11 mm bandwidth). In the experiments, a 34 m/s impact velocity was set using the double-disc method, and five different particle impingement angles (30, 45, 60, 75, and 90°) were used to determine the erosive effect on the outer surfaces of filament wound composite pipes under the influence of 600 μm erodent particles with angular geometry in the test set, complying with the ASTM G76-95 standard. The winding patterns in the lamina (±55 angle-ply laminate region) and zigzag (±55 zigzag region) regions of BFR/EP pipes were determined to have significant effects on solid particle erosion resistance, as evidenced by the SEM images.
采用计算机数控纤维缠绕机（纤维张力为10 N，带宽约11 mm）生产了呈[±55]缠绕结构的玄武岩/环氧树脂复合管。在实验中，使用双盘法设定了34 m/s的冲击速度，并采用五个不同的颗粒冲击角度（30°、45°、60°、75°和90°），以确定在符合ASTM G76 - 95标准的试验装置中，600μm有棱角几何形状的磨蚀颗粒作用下，纤维缠绕复合管外表面的冲蚀效果。扫描电子显微镜图像表明，玄武岩纤维增强环氧树脂（BFR/EP）管的层板（±55角铺层层合板区域）和之字形（±55之字形区域）区域的缠绕模式对固体颗粒抗侵蚀性有显著影响。
