Caractérisation microstructurale 3D et densification locale d'isolants fibreux cellulosiques sollicités en compression

Abstract : In this work, we focus on a thermal insulating panel made of wood fibres. The making process is a non-woven fabric process that generates a high porosity and a very lowdensity material. Thermal properties were first investigated. This paper deals with mechanical properties that are involved in the production line, transport and handling in the construction site. An insulating panel was compressed (33% and 73%) and we followed in situ its internal deformation using X-ray microtomography. The results enlighten a special behaviour that is linked to the low-density structure of the panel. In particular, the fibres are not compressed and the macroscopic deformation of the sample generates only a new organisation of the fibres in the panel. These results are confirmed by morphological measurements that were performed by 3D image analysis.
