The invention belongs to the technical field of railway passenger car interior decoration, and discloses an aramid paper honeycomb motor train unit floor and a preparation method thereof. The aramid paper honeycomb motor train unit floor is prepared from the following raw materials in percentage by mass: 25 to 30 percent of high-density board framework, 8 to 10 percent of aramid paper honeycomb, 10 to 13 percent of resin adhesive, 33 to 37 percent of carbon fiber cured sheet and 13 to 17 percent of iron embedded block. The invention also provides a preparation method of the aramid paper honeycomb motor train unit floor, which comprises the following steps: sequentially placing the release paper a, the carbon fiber curing sheet a, the resin adhesive a, the aramid paper honeycomb, the high-density board framework, the iron embedded block, the resin adhesive b, the carbon fiber curing sheet b and the release paper b, carrying out mold closing and pressurizing treatment, and then carrying out numerical milling treatment to obtain the aramid paper honeycomb motor train unit floor. The aramid paper honeycomb floor is greatly improved in the aspects of tensile strength, compression resistance, sound insulation effect, weight reduction effect and the like, is suitable for running in a motor train unit, and has a wide application prospect.
