The invention belongs to the technical field of anti-drag, anti-fouling and anti-wear composite functional surfaces, and particularly discloses an anti-drag, anti-fouling and anti-wear composite bionic surface layer, a structure of the composite bionic surface layer and a design method of the composite bionic surface layer. The problem that a synergistic resistance-reducing, antifouling and wear-resisting functional surface technology for the ship body is lacked at present is effectively solved. The design method comprises the following steps: (1) simplifying the surface texture of the mirror clam into a triangular groove; and (2) inclining the trend of the triangular groove by 45 degrees, and then rotating by 90 degrees to form a staggered fence-shaped composite groove. The composite bionic surface layer structure is a fence-shaped composite groove which is based on a triangular groove and is combined with a placoid scale groove in the sharkskin surface. The composite bionic surface layer is arranged on the surface of the ship body. Energy conservation and consumption reduction of the ship body in the water flow are facilitated, marine organism fouling is inhibited, the durability problem caused by impact abrasion of the sand-containing water flow is solved, and an environment-friendly antifouling and drag-reducing bionic design scheme is provided.
本发明属于减阻耐磨防污复合功能表面技术领域,具体公开一种减阻防污耐磨的复合仿生表面层、复合仿生表面层的结构及设计方法。有效解决当前缺少用于船体的协同减阻防污耐磨功能表面技术的问题。所述设计方法包括:(1)将镜蛤的表面纹理简化成三角形沟槽;(2)将三角形沟槽的走向倾斜45°,然后旋转90°,形成交错的栅栏形复合沟槽。复合仿生表面层结构是基于三角形沟槽同时结合鲨鱼皮表面的盾鳞沟槽的栅栏形复合沟槽。复合仿生表面层设置在船体表面。本发明有利于船体在水流中的节能降耗、抑制海洋生物污损及解决含沙水流冲击磨损带来的耐用性问题,是一种绿色环保型防污减阻仿生设计方案。
