Definitions

  • the invention relates to a process for a high-iron equipment cabin skirt, in particular to a process for producing a high-strength and light-weight composite material for making a high-iron equipment cabin skirt.
  • the high-speed rail equipment apron is an important part of the standard EMU equipment cabin.
  • the apron carrying capacity, flame retardant capacity and impact resistance have certain requirements, so in the design of the layup, materials and design process All need to be considered; as the technology continues to update, the weight reduction and smoothing in the design process can effectively reduce the resistance of the train during operation, thereby reducing the continuous energy consumption.
