The use of innovative composite materials in aeronautical applications is now facing ever-increasing safety standards that require reliable and relevant responses. Also, enabling the aeronautics industry to understand/predict the thermomechanical response of their materials in different configurations and, ultimately, of their parts and assemblies, is essential. Recent air disasters have revealed that the fire problem is at the heart of the concerns of the aeronautics industry. The demand for suitable and relevant experimental characterisation is therefore strong on the part of the industrialists who have identified a technological lock in the fire resistance of the materials. Thus, the AEROFLAMME project aims to develop new means of experimental characterisation and numerical simulation dedicated to multi-physical analysis of the fire behaviour of composite materials by adopting a multi-scale approach. The aim of the project is to investigate the mechanisms of degradation of the constituent components to the in-flight structure. This project follows the Carnot ESP decolle project (Development of a platform for the study of the mechanical behaviour at fire of thermoplastic composites for the aeronautics) carried out in 2015-2016, and whose main objective was to study the behaviour of aeronautical composite materials subjected to a thermal flux (controlled by calorimeter) combined with a mechanical stress (traction or compression imposed by a mechanical test machine).
