Abstract

Erosion equations were developed to predict the material removal of polyurethane coatings on carbon fiber reinforced plastic (CFRP) surfaces and validated through experimental data. The effects of abrasive properties, process parameters, and organic coating properties (such as fracture toughness and hardness) were considered in the equations. As the erosion angle increased, elastoplastic deformation in the oblique direction and repeated "deformation" in the normal direction were the main reasons for material removal. The ductile erosion behavior was confirmed by experimental data because the maximum erosion rate occurred at an incident angle of 30°. The coefficient and index in the equations were determined by experimental data, and the equations were verified. The developed equations could accurately predict the quantity loss of organic coatings under different particle sizes and particle velocities, and the erosion equations were in good agreement with the experimental data.

建立了塑料磨料去除碳纤维增强聚合物表面有机涂层的侵蚀方程

建立了预测碳纤维增强塑料(CFRP)表面聚氨酯涂层材料去除的侵蚀方程，并通过实验数据进行了验证。该方程考虑了磨料性能、工艺参数和有机涂层性能(如断裂韧性和硬度)的影响。随着冲蚀角的增大，斜向弹塑性变形和法向反复“变形”是材料去除的主要原因。实验数据证实，当入射角为30°时，冲蚀速率最大。通过实验数据确定了方程中的系数和指标，并对方程进行了验证。所建立的方程能较准确地预测不同粒径和颗粒速度下有机涂层的流失量，并与实验数据吻合较好。
