Abstract : The thermal response of a composite material subjected to high heat flux is driven by heat conduction combined with endothermic pyrolysis and exothermic oxidation chemical reactions that change locally the thermo-physical properties and generate decomposition gas flowing throughout the porous charring medium. Heat and mass transfer is also affected by mechanical damage experienced by laminates such as matrix or interfacial cracking the origin of which may be related to internal stresses and thermal loads as well as pore and char formation. The challenge is to analyse concurrently the multi-physics phenomena in order to identify and understand the damage processes.
