Conclusion and outlook

From an aeronautical engineering point of view, understanding mechanical performance in the event of fire is an essential safety issue, as the loss of stiffness, strength and creep resistance can lead to the deformation and collapse of aeronautical composite structures, with catastrophic consequences. Thus, the structural properties of composites under thermal stress (high temperature or flame) are fundamental data for the dimensioning of parts and structures in parts of the aircraft where certification standards are very strict.

In order to establish design rules, this article provides information on the specific methodology and characteristic behaviors and properties needed to better understand thermomechanical couplings within composite materials subjected to critical conditions in service. In particular, this requires the use of specific test facilities that...
