混杂纤维复合材料螺旋桨的铺层结构设计与模压成型工艺
Ply structure design and molding process of hybrid fiber composite propeller
摘要
Abstract
In order to promote the integrated research on the design and molding process of composite propeller products and emphasize the role of fiber hybrid in the development of high damping and high performance blades,the small-size composite propeller was taken as an investigation object.Based on its surface and geometric charac-teristics,the material and ply design of the hybrid fiber composite blade were carried out,which results in two pro-peller ply schemes under the hybrid modes of carbon fiber(CF)and kevlar fiber(KF)respectively.By employing the ACP module in ANSYS Workbench platform,the finite element modelling of anisotropic composite material was conducted,which can be consistent with the actual structural characteristics of the blade.According to the guidance of simulation analysis,the hybrid fiber composite propeller sample model was fabricated by using the molding process of prepreg.Through the static loading test and modal measurement test upon the manufactured propeller blade,the comparisons between experimental and calculation data of its static stiffness and modal frequencies from the 1st to 3rd stage are obtained.The good agreement not only verifies the reliability of the modeling method of com-posite propeller based on ANSYS ACP,but also verifies the feasibility of manufacturing hybrid fiber composite blade samples by molding process.关键词
