This study focuses on the link between damage development and permeability evolution of composite laminates. By making use of an original device, measurement of the permeability of composite pipes under pressure and quantification of leak paths were conducted. Presented results show that very few (about one per 100 cm2) leak paths are sufficient to increase the permeability of several orders of magnitude, suggesting the existence of a preliminary phase characterized by a progressive development of a few cracks. Damage modelling and identification are proposed, allowing this phase to be taken into account. From this modelling coupled with a simplified representation of the crack network, prediction of leak path density is provided.< Leer menos
