The Rheology of Concentrated Suspensions of Fibers and Spheres

Abstract

A review and summary are presented on the existing scientific and technical literature on the viscosity and elasticity of concentrated fiber suspensions, including reinforced plastics. Also discussed is the experimental capillary rheometry of model suspensions of glass fibers in viscous silicone oils. At high volume fraction fibers such suspensions are pseudoplastic, exhibit a yield stress in shear, have large capillary entrance corrections, but show no die swell. A brief account is given of the influence of fiber breakage on suspension viscosity in capillary flow and on the best choice of technique for mixing such suspensions. (Author modified-PL)
