Nowadays, composite materials are often used as construction materials  not only in the aviation industry. In general, composite materials mean  technical material. Although, they are  heterogeneous in their  structure, they are  understood to be homogeneous. Composites are formed by a composition of at least two chemically and physically different materials. This  article deals with fire resistance of composite materials, regularly  used in aviation industry. The flammability tests were performed as a part of the project "Simulation of Intervention in Air Accidents," where several materials used in aircraft constructions and interiors were tested. The fire resistance of composite materials is evaluated in the article based on the Maximum Average Rate of Heat Emission (kW/m2). The investigated samples are both of core and core-free sandwich structures. The flammability test was performed on both sides of the sample (smooth and rough). The fire resistance test  was performed on the basis of EN 45545.
