Analysis of fire test methods and airworthiness requirements for materials in the cabin of civil aircraft

Abstract The safety of aircraft cabin materials is related to the safety of passengers and aircraft. With the development of science and technology, the types of materials are becoming more and more abundant, with frequent applications in the aircraft cabin, cargo compartment, and other locations. A large number of these materials improve the economic comfort of the aircraft. When a fire occurs, the performance of the materials involved can significantly influence the fire’s progression, which in turn affects the safety of passengers and the aircraft. Additionally, it can impact emergency evacuation procedures. To enhance safety in aircraft research, development, and manufacturing, it is essential to understand the flame-retardant properties of materials used in aircraft. Scientific methods must be employed to verify the fireproofing capabilities of these materials, and data-driven evaluations should assess their flame-retardant properties. This is crucial to ensure the safety of passengers and the aircraft itself. In the event of a fire, effective materials can slow the spread of flames, allowing passengers to evacuate promptly and increasing their chances of survival. By analyzing the cabin material fire test verification method and airworthiness requirements, the aircraft cabin material fire requirements are outlined to provide guidelines for the commercial aircraft cabin material fire verification work, to guide the aircraft design process of cabin material selection, and to accelerate the pace of airworthiness certification.
