The invention provides a composite material connecting structure for a railway vehicle and a forming method. The structure comprises a first top plate skin, a second top plate skin, a main beam carbonplate and a carbon fiber cover plate, wherein the first top plate skin and the second top plate skin are glued on the top surface of the main beam carbon plate; the first top plate skin is spliced with the second top plate skin; at least one row of holes located in the two sides of the splicing position are formed in the top face of the main beam carbon plate; the first top plate skin is providedwith at least one row of first through holes in one-to-one correspondence with the at least one row of holes in one side; the second top plate skin is provided with two rows of second through holes in one-to-one correspondence with the at least one row of holes in the other side; the first top plate skin and the main beam carbon plate are riveted with the corresponding holes through the first through holes, and the second top plate skin and the main beam carbon plate are riveted with the corresponding holes through the second through holes; and the carbon fiber cover plate is arranged on theouter surface of the splicing position of the first top plate skin and the second top plate skin in an adhesive covering mode. The connecting structure can adapt to connection of rail vehicle composite materials, and the air tightness and the structural strength of connection can be guaranteed.

    本发明提供轨道车辆用复合材料连接结构及成型方法,包括第一顶板蒙皮、第二顶板蒙皮、主梁碳板、碳纤维盖板,第一顶板蒙皮与第二顶板蒙皮均胶粘设于主梁碳板的顶面,第一顶板蒙皮与第二顶板蒙皮拼接,主梁碳板的顶面设有位于拼接处两侧的至少一排孔,第一顶板蒙皮设有与其中一侧的至少一排孔一一对应的至少一排第一通孔,第二顶板蒙皮设有与另一侧的至少一排孔一一对应的两排第二通孔,第一顶板蒙皮与主梁碳板通过第一通孔与对应的孔铆接,第二顶板蒙皮与主梁碳板通过第二通孔与对应的孔铆接;碳纤维盖板通过胶粘覆设于第一顶板蒙皮与第二顶板蒙皮拼接处的外表面。本发明能适应轨道车辆复合材料的连接,且能够保证连接的气密性和结构强度。
