The invention belongs to the technical field of railway vehicle body structures, and particularly relates to a railway vehicle fairing composition structure and a fairing forming method.The fairing composition structure comprises a fairing, a sealing rubber strip, a hinge and a lock, and the fairing comprises an outer panel, a reinforcing plate and an inner panel; the outer panel, the reinforcing plate and the inner panel are all made of fiber-reinforced halogen-free flame-retardant epoxy resin matrix composite materials and are sequentially stacked and fixedly connected through adhesive films. The structural design is a composite material interlayer which is fixedly connected through an outer panel, a reinforcing plate, an inner panel and an adhesive film. And curing is carried out under the heating and pressurizing conditions, so that the whole flow guide cover composition structure has good rigidity and strength and has the characteristics of good impact resistance, fatigue resistance and the like, and meanwhile, the weight of the whole flow guide cover can be reduced by about 30%.

    本发明属于轨道车辆车体结构技术领域,尤其涉及一种轨道车辆导流罩组成结构及导流罩的成型方法,包括导流罩、密封胶条、铰链、锁,导流罩包括外面板、加强板和内面板;外面板、加强板、内面板所采用的材料均为纤维增强无卤阻燃环氧树脂基复合材料制备,依次利用胶膜叠放固定连接;其结构设计成复合材料夹层,通过外面板、加强板、内面板及胶膜固定连接。在加温加压条件下固化,使整个导流罩组成结构具有良好的刚度、强度,并具良好的耐冲击、耐疲劳等特性,同时整个导流罩的重量可降低30%左右。
