Composite material connecting joint

The invention belongs to the field of airplane structure design and relates to the improvement in an airplane control plane connecting joint which is a detachable composite material double-lug joint with linings. The joint is characterized in that the joint comprises a detachable composite material control plane connecting joint body 1, the two ends of the joint body are connected with the metal linings 2 in a glued manner, a control plane skin 3 is recessed downwards, a notch is formed in the control plane skin 3, and the control plane connecting joint body 1 is connected with the control plane skin 3 through supporting plate nuts. The composite material connecting joint replaces a metal connecting joint, the appearance of the front edge of a control plane is well guaranteed, the joint is located on the front face of the center of a rotary shaft due to the n-shaped joint recessed inwards, and the balance weight of the control plane is reduced. 本发明属于飞机结构设计领域，涉及对飞机舵面连接接头的改进，它是个带衬套可拆卸的复合材料双耳接头。其特征是：可拆卸的复合材料舵面连接
