The invention discloses a flexible composite skin capable of being applied to a shear deformation wing and a manufacturing tool and method, and relates to the technical field of aviation. The problems that the thickness of the skin is large, the driving burden is large, the manufacturing steps are tedious and chambering fails in the shearing deformation process of the skin due to the fact that a fiber reinforcement body of an existing flexible composite skin is a fiber bundle distributed in a one-way mode and a manufacturing process that the fiber bundle is flatly laid in a double-layer mode is adopted are solved. A plurality of groups of columnar supporting structures are cured in a flexible rubber matrix in parallel at equal intervals, and a fiber cloth reinforcing body is flatly laid above the plurality of groups of columnar supporting structures and is cured in the flexible rubber matrix; the fiber cloth reinforcement body and the plurality of groups of columnar supporting structures are cured in the flexible rubber matrix to form the flexible composite skin. The invention is used for realizing the functions of smooth continuous shear deformation, improvement of bearing rigidity, optimization of aerodynamic performance and the like.

    可应用于剪切变形机翼的柔性复合蒙皮、制作工装及方法,它涉及航空技术领域。本发明解决了现有的柔性复合蒙皮的纤维增强体为单向分布的纤维束,并采用双层平铺纤维束的制作工艺,存在蒙皮厚度大,驱动负担大,制作步骤繁琐,且在蒙皮剪切变形过程中也导致扩孔失效的问题。本发明的多组柱状支撑结构等间距且相互平行固化于柔性橡胶基体中,多组柱状支撑结构上方平铺有纤维布增强体,所述纤维布增强体固化于柔性橡胶基体中,纤维布增强体和多组柱状支撑结构固化于柔性橡胶基体中形成柔性复合蒙皮。本发明用于实现光滑连续剪切变形、提高承载刚度以及优化气动性能等功能。
