The invention provides a light composite material sandwich wing rib and a preparation method, and relates to the technical field of aircraft manufacturing, the light composite material sandwich wing rib comprises a wing rib outer contour and at least two inclined web pipes, the interior of the wing rib outer contour is of a hollow structure, the inclined web pipes are arranged in the hollow structure, and the two ends of each inclined web pipe are fixedly connected with the opposite sides of the wing rib outer contour correspondingly; every two adjacent inclined web pipes and the outer contours of the wing ribs form a triangular structure; the wing rib outer contour comprises a wing rib edge strip and a wing rib web plate, the wing rib web plate forms an outer frame of the wing rib outer contour, the wing rib edge strip covers the pneumatic side of the wing rib web plate, and after a cavity formed by the wing rib edge strip and the wing rib web plate is filled with reinforcing matter, a reinforcing filling area is formed. Through the reinforcing substance between the wing rib web plate and the wing rib edge strip made of the composite material and the inclined web pipe for reinforcing, the weight of the whole wing rib is reduced, meanwhile, the effective strength of the wing rib is guaranteed, and the wing rib is suitable for light aircrafts such as solar aircrafts.
本发明提供一种轻型复合材料夹芯翼肋及制备方法,涉及飞行器制造技术领域,包括:翼肋外轮廓和至少两根斜腹管,翼肋外轮廓的内部为中空结构,斜腹管设置在中空结构中,斜腹管的两端分别与翼肋外轮廓的相对侧固定连接,相邻的两根斜腹管与翼肋外轮廓构成三角形结构;翼肋外轮廓包括翼肋缘条和翼肋腹板,翼肋腹板构成翼肋外轮廓的外框,翼肋缘条覆盖在翼肋腹板的气动侧,在翼肋缘条和翼肋腹板构成的腔室中填充加固物质后,形成加固填充区。通过复合材料制成的翼肋腹板和翼肋缘条之间加固物质,以及加固用的斜腹管,降低整体翼肋重量的同时保证翼肋的有效强度,适用于太阳能飞行器等轻型飞行器。
