|Summary||This paper presents a methodology for evaluation of the fire performance of composite material designs for aircraft structural applications. While compatible with civil aviation authority requirements, the tests outlined are intended primarily for screening various potential design options rather than for certification purposes. The developed test approach is demonstrated via a study of design options for a 'fireproof' composite aircraft engine enclosure. This study demonstrates that various composite material designs offer significant potential for fire containment, but also shows that the level of strength retained by composite structures during a fire event is very low in the area of flame impingement.
