Abstract

Fiber suspensions being mixed by an impingement mixer behave differently than liquids alone. The shear viscosity of a given suspension, measured at a strain rate which is characteristic of the flow in the mixer, is the dominant parameter describing the behavior of the suspension. Good mixing quality is obtained when the effective Reynolds number, based on the shear viscosity of the suspension, is about 200 or greater. Extrapolation of published data on the viscosity of milled glass fiber/RIM resin suspensions suggests that impingement mixers can handle between 80 and 95 percent of the maximum fiber volume fraction for a given fiber length. Therefore, impingement mixers should be quite useful in almost all reinforced RIM applications involving milled glass fibers or similar reinforcements.
