- Abstract
- Rheological model of impregnation of foamed polyurethane with slip structure which includes elastic and ductile elements and also an element of "dry friction" which is determined by limit shear stress was presented. It was got an equation of variable current of a sodden composition in pore canals which defines a change of deformation of foamed polyurethane model during the process of impregnation by different elastic properties of perform, rheological properties of slip and geometry of pore canal.
