The invention discloses a voronoi-based fiber reinforced composite material 3D printer wing and a design method thereof. The wing is mainly composed of an outer contour and a frame structure in the contour. The frame structure is composed of a plurality of mapped Thiessen polygons obtained by constructing a voronoi structure by a group of initial sites in a region and carrying out centroid processing and equal proportion mapping on the voronoi structure, the outer part of the outer contour is wrapped by the skin, the frame structure is connected with the inner surface of the skin, the frame structure is filled in the whole wing, and the frame structure is connected with the inner surface of the skin. On the premise that the bearing capacity is guaranteed, a fiber printing path of a frame structure is reasonably planned, and then integrated forming manufacturing of the composite material wing is achieved. And the composite material wing structure can be integrally formed through a fiber reinforced printing technology, so that the manufacturing time and the production cost of the composite material wing are reduced.
本发明公开了一种基于voronoi的纤维增强复合材料3D打印机翼及其设计方法,所述机翼主要由外轮廓及轮廓内部的框架结构组成,所述框架结构由区域内的一组初始站点通过构造voronoi结构并对其进行质心化处理和等比例映射的方式得到若干个映射后的泰森多边形组成,所述外轮廓外部被蒙皮包裹,框架结构则和蒙皮的内表面连接,所述框架结构填充在整个机翼内部,在保证承载能力的前提下通过对框架结构的纤维打印路径进行合理规划进而实现复合材料机翼的一体化成型制造,本发明提供了一种结构形式简单,承载能力强,稳定性良好且可以通过纤维增强打印技术一体化成型的复合材料机翼结构,从而降低复合材料机翼的制造时间和生产成本。
