Summary Fire‐induced decomposition of composite materials involves complex and coupled multi‐physics phenomena experienced for instance in standard tests (cone calorimeter, FAR 25.856(b):2003 and ISO 2685:1998(e)). It is proposed to address this issue in a simplified laboratory facility using a gas burner embedded with coupled measurement techniques to assess all desired physical quantities. A focus is given in this study on non‐intrusive (no coating required) digital image correlation (DIC) and infra‐red thermography (IRT) measurements. Out‐of‐plane displacement and temperature of the unexposed surface were accurately measured as a function of time to investigate the 3D fire behaviour of a composite laminate used in the aircraft industry. Those complementary measurements are carried out on a purpose‐made experimental set‐up in order to provide relevant and correlated information from FOLKI‐D algorithm and to identify the damage mechanisms.
