PMI foam is utilized in the railway industry, primarily as a core material in lightweight sandwich composite structures. Its properties offer potential benefits for modern rolling stock design, focusing on weight reduction, energy efficiency, and structural performance.
Application Scenarios:
PMI foam cores, typically in fire-retardant grades or as part of a certified system, are used or considered for various components in rolling stock (high-speed trains, commuter trains, metro cars, trams):
1.Interior Components:
- Flooring Systems: Lightweight, stiff sandwich panels for sub-floors.
- Ceiling Panels & Linings: Reducing overhead weight and providing insulation.
- Partition Walls & Bulkheads: Lightweight separation structures.
- Cabinets, Luggage Racks, and Interior Fittings: Weight saving in non-primary structural elements.
- Tables: Lightweight passenger tables.
- Toilet Modules: Pre-fabricated lightweight modules.
2.Exterior Components:
- Body Shell Structures (Side Walls, Roofs): As a core material in large sandwich panels contributing to the main car body structure, offering weight savings and insulation.
- Front Ends / Driver Cabs: Used in complex curved structures where aerodynamics and weight are important.
- Doors: Lightweight door leaves.
- Skirts and Fairings: Aerodynamic components below the main car body.
3.Other Potential Applications:
HVAC Ducting: Lightweight and insulated air distribution systems.
