The invention discloses a composite material hollow joint structure and a layering method thereof, the joint is of a structure with two hollow ends, the main body is cylindrical, the main structure is the main structure of the joint and is used for connecting a machine body, the structure is gradually transited to an inclined plane, and the beveling design is used for conveniently inserting and connecting a metal lining; an internal spline is arranged on the surface of the metal lining, connecting bosses are designed at the two ends of the metal lining, the composite material and the lining are prevented from sliding, an ear-shaped protrusion is arranged on the upper portion of the middle of the connector, a through hole is formed in the ear-shaped protrusion and used for installation of a pin, and the connector can be fixed to other structures. The overall structure of the connector is optimized, the inner spline area laying layer is nested on an inner spline of the metal lining, the outer equal-thickness area laying layer is laid on a boss of the metal lining, the connecting strength of metal and a composite material is guaranteed, one end of the inner main rod first area laying layer is embedded into a connector connecting area and is directly connected with the connector connecting area, and the other end of the inner main rod first area laying layer is directly connected with the connector connecting area. And the continuity of the whole structure is ensured.

    本发明公开了一种复合材料中空接头结构及其铺层方法,该接头为两端中空结构,主体呈现圆柱形是接头的主要结构,用于连接机身,结构逐渐过渡到一个斜面,这种斜切设计是为了便于插入和连接金属衬套,金属衬套表面带有内花键并在两端设计了连接凸台,防止复合材料与衬套发生滑动,在接头中部偏上的位置有一个耳状突起,上面有一个贯穿孔,用于销钉的安装,使接头可以固定在其他结构上。本发明优化接头的整体结构,所述内层花键区铺层嵌套在所述金属衬套内花键上,所述外层等厚区铺层贴铺在所述金属衬套凸台上,保证了金属与复合材料的连接强度,所述内层主杆一区铺层一端嵌入接头连接区,与其直接相连,保障了整体结构的连贯性。
