The objective of this review is to elucidate the rheological behavior of glass fiber suspensions whose suspendingmediums are non-Newtonian fluids. In particular, this review focuses on determining the impact of fiberconcentration, aspect ratio, orientation distribution, interaction with the suspending medium, and suspendingmedium viscoelasticity on the rheology of glass fiber composite fluids. The presence of glass fiber can inducea yieldlike behavior, causing shear thinning to occur at reduced shear rates. Glass fiber can impede the elasticproperties of the suspending medium but enhance the first normal stress function. Large stress overshoots inboth the shear and normal stress growth functions are observed that are associated with changes in fiberorientation. Upon cessation of flow, stress relaxation follows that of the suspending medium but fibers retaintheir orientation. The presence of glass fiber can induce extension rate thinning and suppress the strainthickening behavior of the suspending medium.
