The invention provides a flexible skin and a preparation method and application thereof, and belongs to the technical field of skins. The flexible skin comprises an elastomer layer, a corrugated plateand a reinforcing plate, wherein the corrugated plate is arranged on one side of the elastomer layer, and the reinforcing plate is vertically arranged in a middle corrugated groove of the corrugatedplate and transversely arranged on the outermost side of the corrugated plate. In the flexible skin provided by the invention, the corrugated plate is used as an internal framework and a force bearingpart to achieve the function of bearing aerodynamic load, so that the problem of insufficient rigidity inside and outside the surface of the traditional flexible skin is solved; meanwhile, the corrugated plate is used as an assembly for controlling the Poisson effect to reduce the Poisson effect when the skin deforms; the reinforcing plate has the capability of bearing aerodynamic load when the skin deforms; the elastomer layer is used as a smooth skin outer layer, can reduce resistance, and has good rapid deformation and recovery capability. The flexible skin with the specific structure is high in aerodynamic load bearing capacity and deformation capacity, and the Poisson effect is not obvious.
本发明提供了一种柔性蒙皮及其制备方法和应用,属于蒙皮技术领域。本发明提供的柔性蒙皮,包括弹性体层、波纹板和加强板,所述波纹板设置于弹性体层的单面,所述加强板竖直设置于所述波纹板的中间波纹槽内和横向设置于所述波纹板的最外侧。本发明提供的柔性蒙皮中,波纹板作为内部骨架及承力部件起到承受气动载荷的作用,解决了传统柔性蒙皮面内和面外刚度不足的问题,同时作为控制泊松效应的组件在蒙皮变形时减小泊松效应;加强板在蒙皮变形时具有承受气动载荷的能力;弹性体层作为光滑的蒙皮外层,能够减小阻力,而且还具有良好的快速变形和回复能力。本发明提供的具有特定结构的柔性蒙皮承受气动载荷能力和变形能力强、泊松效应不明显。
