Most of the PI/PMI structural foams have been used as composite sandwich materials and have been successfully introduced into many applications. There are currently composite sandwich applications in the fields of radomes, stealth, trains, ships, automobiles and aviation. Aerospace, medical, sporting goods. PMI foam composite products have grown rapidly in the global market. Since the 1970s, foam has been used in many aerospace and aerospace vehicles, including McDonnell Douglas MD11 flap deflectors and air intakes.
Westland Helicopter's "Bobcat", "Sea King" main and tail rotors; Airbus A320 spoiler, aircraft cabin airtight partition; European helicopter company EC135, NH90 main tail rotor; Boeing and West Corosky's joint development of the RAH-66 "Comanche" rotor. In space, PMI foam has been applied to the load section fairings, interstages, intermediates, heat shields and thruster nose cone structures of the Deltal launch vehicle.
In transportation, PMI foam has been applied to the train head of Japan Shinkansen E4 train, the head of the European express train, the self-supporting truck body of SchindlerTechnic of Switzerland, the middle section of the tram of Germany Duewag, the Italian Ferrari sports car, The body of the F1 car, etc. PMI foam is also used in medical bed boards from companies such as Siemens and the hulls of Norwegian high-speed surface effect patrol boats.
The excellent properties of the foam make it one of the ideal lightweight materials in materials science. Combining PMI foam with other materials and processing techniques is conducive to the lightweight development of automobiles. With the continuous development and maturity of materials lightweight technology, including design, production process, assembly, connection and material properties, the future multi-material lightweight structure based on composite materials is the development trend of automotive lightweight and automotive exterior parts materials. Through the combination and complement of different materials, structures and manufacturing processes, the modularity of design and manufacturing can be easily and conveniently achieved to achieve the best combination of materials and parts. At present, the lightweight technology of automobiles is still in an immature stage, and there will be a lot of room for development in the future.
