Zusammenfassung: Fire in aviation is a significant safety hazard to aircraft and their occupants. New electric powerplant technologies and the increased use of flammable fibre composite materials in aircraft structures have directed more attention to fire protection. Great effort was made in developing materials for improving the fire resistance of fibre composites. This paper concentrates on potential fire sources in aircraft and characteristics of different fire protection materials for fibre composites and their lightweight potential. Therefore, various lightweight fire protection designs for engine compartments were analyzed. To evaluate these designs, fire tests on unprotected and protected fibre composite structures under load were conducted. Therefore, this paper presents the test device and the experimental results. Furthermore, recommendations on designing fireproofed lightweight structures under EASA certification requirements for engine compartments are given.
