The invention discloses a rain-erosion-resistant protection method for a rigid composite material part, and belongs to the technical field of composite material protection. In order to solve the problem that a rigid composite part is easily impacted and damaged by liquid drops in a rain erosion scene, a method of removing a preset thickness of a rigid layer and laying a fiber-reinforced flexible composite material as a flexible layer is mainly adopted, and the flexible layer and the rigid layer are connected through in-situ curing of flexible resin, so that the overall protection performance is improved. According to the method, the synergistic effect that the rigid part bears the structural load and the flexible part absorbs impact energy can be achieved, and the rain erosion resistance, sand erosion resistance and impact resistance of a workpiece are remarkably improved.

    本发明公开了一种刚性复合材料制件的耐雨蚀防护方法,属于复合材料防护技术领域。本发明为解决刚性复合材料制件在雨蚀场景中易受液滴冲击损伤的问题,主要采用去除刚性层预设厚度并铺敷纤维增强柔性复合材料作为柔性层的方法,通过柔性树脂原位固化连接柔性层与刚性层,从而提高整体防护性能。本发明能够实现刚性部分承载结构载荷、柔性部分吸收冲击能量的协同作用,显著增强制件的耐雨蚀、耐砂蚀和抗冲击能力。
