The invention relates to the field of composite materials, and provides a curved surface composite material connecting structure, a forming method and a rail vehicle. The curved surface composite material connecting structure comprises a pair of composite material curved surface skins and a connecting beam, wherein the pair of composite material curved surface skins is spliced on the outer surfaceof the connecting beam; the curved surface composite material connecting structure further comprises a plurality of thickening sheets which are fixedly arranged on the bonding surface of each composite material curved surface skin correspondingly; the plurality of thickening sheets are arranged on the bonding surface of each composite material curved surface skin at intervals; the bonding surfaceof each composite material curved surface skin is in contact with the outer surface of the connecting beam through the thickening sheets; a gap is formed between each composite material curved surface skin and the outer surface of the connecting beam; and the gaps are filled with adhesive layers. According to the curved surface composite material connecting structure, the forming method and the rail vehicle, the machining, connecting and assembling difficulty of the whole composite material connecting structure can be reduced, so that the structure is firmer when the composite material curvedsurface skin is bonded with the connecting beam.
本发明涉及复合材料领域,提供曲面复合材料连接结构、成型方法及轨道车辆。该曲面复合材料连接结构包括一对复合材料曲面蒙皮,以及连接梁,一对复合材料曲面蒙皮拼接设于连接梁的外表面,其还包括分别固设于每个复合材料曲面蒙皮粘接面的多个增厚片,多个增厚片间隔排布在复合材料曲面蒙皮的粘接面,每个复合材料曲面蒙皮的粘接面通过增厚片与连接梁的外表面接触,且在每个复合材料曲面蒙皮与连接梁的外表面之间形成间隙,间隙中填充粘接胶层。本发明能够降低整个复合材料连接结构的加工、连接、装配难度,使得复合材料曲面蒙皮在与连接梁粘接时结构更牢固。
