摘　　要：介绍了用于飞机燃油箱以及干舱填充用的防火防爆网状聚氨酯泡沫材料最初的发展以及改进和使用情况。网状聚氨酯泡沫是一种轻质、柔性材料 ,它由相互连接的经络构成了空间“骨架”结构 ,这种结构实际上是一种三维的防火屏蔽。网状聚氨酯泡沫材料的防火防爆性能是经过实战检验的 ,并且在应用中不断得以改进。填充在飞机燃油箱中的网状聚氨酯泡沫材料能有效地减少由于射弹、电火花、雷击以及静电等原因引起的燃油箱过压 ,从而有效地减少了飞机的易损性 。The paper describes the initial development, evolution, and use of reticulated polyurethane foam as an explosion suppression material in fuel tanks and dry bays. The material is a lightweight flexible foam composed of a skeletal matrix of tiny interconnecting strands which act as a three-dimensional fire screen. Reticulated polyurethane foam used as an explosion suppressor is a combat-proven system refined from experience that will minimize fuel tank overpressure that caused by: gunfire; electrical ignition; lightning strikes; and electrostatic discharges. It functions as a multiple hit, passive defense system to reduce vulnerability and increase survivability.
