Permeability of porous foamy materials
V. Langlois, V. H. Trinh, C. Lusso +4
In this paper, we study the effects of both the amount of open cell walls and their aperture sizes on solid foams permeability. FEM flow simulations are performed at both pore and…
Achievement of acoustical properties of foam materials by tuning membrane level: Elaborations, models and experiments
Van Hai Trinh, Camille Perrot, Vincent Langlois +2
This work presents a combined numerical and experimental approach to characterize the macroscopic transport and acoustic behavior of foam materials with a membrane cellular structu…
Coupled elasticity in soft solid foams
François Gorlier, Yacine Khidas, Olivier Pitois
Elasticity of soft materials can be greatly influenced by the presence of air bubbles. Such a capillary effect is expected for a wide range of materials, from polymer gels to conce…
Optimal strengthening of particle-loaded liquid foams
François Gorlier, Yacine Khidas, Abdoulaye Fall +1
Foams made of complex fluids such as particle suspensions have a great potential for the development of advanced aerated materials. In this paper we study the rheological behavior…
Strengthening of foamed composite materials
Yacine Khidas, Benjamin Haffner, Olivier Pitois
We investigate the shear elastic modulus of soft polymer foams loaded with hard spherical particles and we show that, for constant bubble size and gas volume fraction, strengthenin…
