The Dynamic Behavior of a Concentrated Polymeric Suspension Containing Non-Brownian Glass Fibers in Simple Shear Flow
In this paper we study the dynamic behavior of a concentrated short glass fiber suspension subject to simple shear flow. In particular we are interested in determining the relationship between the stress growth functions (shear and first normal stress) and the evolution of the fibers’ orientation distribution within the sample. Stress growth experiments, in start-up of flow, are performed on a ...
متن کاملRheology of concentrated xanthan gum solutions: Oscillatory shear flow behavior
Using a strain-controlled rheometer, the dynamic viscoelastic properties of aqueous xanthan gum solutions with different concentrations were measured over a wide range of strain amplitudes and then the linear viscoelastic behavior in small amplitude oscillatory shear flow fields was investigated over a broad range of angular frequencies. In this article, both the strain amplitude and concentrat...
متن کاملFiber Orientation Kinetics of a Concentrated Short Glass Fiber Suspension in Start up of Shear Flow
The common approach for simulating the evolution of fiber orientation during flow in concentrated suspensions is to use an empirically modified form of Jeffery’s equation referred to as the Folgar-Tucker model. Direct measurements of fiber orientation were performed in startup of shear flow for a 30 wt % short glass fiber-filled polybutylene terephthalate (PBT-30); a matrix that behaves similar...
متن کاملFiber Orientation Kinetics of a Concentrated Short Glass Fiber Suspension in Startup of Simple Shear Flow
The common approach for simulating the evolution of fiber orientation during flow in concentrated suspensions is to use an empirically modified form of Jeffery’s equation referred to as the Folgar-Tucker (F-T) model. Direct measurements of fiber orientation were performed in the startup of shear flow for a 30 wt % short glass fiber-filled polybutylene terephthalate (PBT-30); a matrix that behav...
متن کاملViscosity of a concentrated suspension of rigid monosized particles.
This paper addresses the relative viscosity of concentrated suspensions loaded with unimodal hard particles. So far, exact equations have only been put forward in the dilute limit, e.g., by Einstein [A. Einstein, Ann. Phys. 19, 289 (1906) (in German); Ann. Phys. 34, 591 (1911) (in German)] for spheres. For larger concentrations, a number of phenomenological models for the relative viscosity was...
