Aviation aircraft requires that the materials used should be as light as possible on the basis of satisfying other properties to save fuel and increase load capacity. A sponge-like, lightweight PMI foam material has a flame resistance of 800 ° F. Even at this temperature, the PMI foam material is only carbonized and decomposed, which can reduce accidents in flight. The material can also extend the lifespan of aircraft passengers by 2-5 minutes in the event of an external fuel fire. At present, aviation giants such as Boeing, Lockheed Martin, General Motors, Airbus, and Donnell use PMI foam extensively on the aircraft they manufacture.
Not only large aircraft, but also civilian small aircraft, PMI foam is widely used as a sandwich material. Due to the excellent properties of PMI foam, it has become an ideal foam material for aircrafts and other aircraft. On the spacecraft, such as the space shuttle, space station, Mars probe, and lunar module, due to its special operating environment, the materials on the components must not only withstand the high temperatures brought by flight, but also have to be lightweight and flame retardant. , Sound absorption, shock absorption and other performance.
PMI foam is used as low-temperature storage tanks, wave-transmitting materials, fuselage insulation systems, aircraft seats, and PMI can be made into honeycomb structural materials. The thermal insulation system made of PMI foam-aluminum-PMI foam can maintain good thermal insulation performance at -217 ℃ and supersonic flight environment 204 ℃.
