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.
