The invention discloses a composite material floor and a railway vehicle, and relates to the technical field of railway vehicles. The composite floor comprises an upper skin, a lower skin and reinforcing ribs arranged between the upper skin and the lower skin, one ends of the reinforcing ribs are connected with the upper skin, and the other ends of the reinforcing ribs are connected with the lower skin. A weight reduction material is filled between the upper skin and the lower skin; and at least one of the upper skin, the lower skin and the reinforcing ribs is made of a carbon fiber material. Compared with a metal material in the prior art, the composite material floor has the advantages that the weight can be effectively reduced, the weight of the whole floor structure is reduced by more than 35% compared with a stainless steel structure, and the train operation energy consumption is effectively reduced. In addition, the composite material floor is made of the carbon fiber material, the welding amount can be effectively reduced, deformation in the welding process can be avoided, the workpiece precision is further improved, the later procedure adjusting and repairing operation is reduced, and the working efficiency is improved.
本发明公开了一种复合材料地板及轨道车辆,涉及轨道车辆技术领域。复合材料地板包括上蒙皮、下蒙皮以及设置于上蒙皮与下蒙皮之间的加强筋,加强筋的一端连接上蒙皮、另一端连接下蒙皮;上蒙皮与下蒙皮之间填充有减重材料;上蒙皮、下蒙皮、加强筋中的至少一者为碳纤维材质。本发明中的复合材料地板相比于现有技术中的金属材质,可有效减重,整体地板结构较不锈钢结构减重35%以上,有效降低列车运行能耗。另外,本发明中的复合材料地板采用碳纤维材质,可有效减少焊接量,避免焊接过程中的形变,进而提高制件精度,减少后工序调修作业,提高工作效率。
