Additive manufacturer 3T RPD has developed a flame retardant nylon that can be used in aircraft. The nylon can be used in 3D printing to manufacture plastic parts and is particularly suited for panel applications in aircraft interiors. If a fire occurs the nylon releases an inert halogen gas, which starves flames of oxygen and extinguishes the fire. The new material has tested to the EU's joint aviation requirement standard for flammability and smoke generation and meets requirements for toxic gas generation. The firm anticipates that the nylon will be used in air ducts, outlet valves, fairings and clips.
