Structural characterization of solid foams

Résumé

Tomographie aux rayons X Matériaux cellulaires Analyse d'images MEB 3D For being a useful contribution to the understanding of the properties of solid foams, the characterization of the structure of solid foams has to be performed at different scales. The microstructure of the solid part of the foams has to be analyzed. For this, standard SEM observations are often used. The most important aspect (and the most problematic) remains the characterization of the porous architecture of these materials. The methods introduced in this paper concern both scales and the article discusses the specificity of the experiments in the case of porous materials. X-ray tomography is described in more details because it becomes widely used for this purpose. The paper also shows how the obtained 3D images (sometimes obtained during deformation) can be processed to yield important morphological parameters describing the foams.
