The invention relates to the technical field of rail transit, in particular to a modular composite apron board for a rail vehicle. The apron board comprises an outer skin, an inner core and an inner skin, and the inner core is located between the outer skin and the inner skin. The inner skin comprises a middle module and side modules, the side modules are located at the two ends of the middle module, bent parts are arranged on the sides, facing the middle module, of the side modules, the bent parts are bent towards the outer skin, and the inner sides of the bent parts are bonded to the inner side of the middle module; an inner flange is arranged on the top side of the outer skin and abuts against the outer side of the inner skin, outer flanges are arranged on the other edges of the inner skin except for the top side, the outer flanges abut against the inner side of the inner skin, and a cavity for containing the inner core is defined by the inner flanges and the outer flanges. The problems that a traditional composite material apron board is complex in structure coupling, poor in mold universality, low in forming efficiency, high in preparation cost and the like are solved, and efficient and low-cost preparation of the composite material apron board is achieved.

    本发明涉及轨道交通技术领域,尤其涉及一种轨道车辆模块化复合材料裙板。裙板包括外蒙皮、内芯和内蒙皮,内芯位于外蒙皮和内蒙皮之间;内蒙皮包括中间模块和边模块,边模块位于中间模块的两端,边摸块朝向中间模块的一侧设置有弯折部,弯折部向外蒙皮方向弯折,弯折部的内侧粘接在中间模块的内侧;外蒙皮的顶侧设置有内翻边,内翻边与内蒙皮的外侧抵接,内蒙皮除顶侧的其他边缘设置有外翻边,外翻边与内蒙皮的内侧抵接,内翻边和外翻边围成容纳内芯的空腔。通过本发明解决了传统复合材料裙板结构耦合复杂、模具通用性差、成型效率低及制备成本高等问题,实现了复合材料裙板的高效、低成本制备。
