In the present paper an account is given of the effects of matrix rheology, fiber length and concentration on the viscous properties of suspensions. The flow properties of concentrated fiber suspensions of different silicone oils and glass fibers were investigated by capillary viscometer. The generalized flow behavior at high shear rates was given independent of the oil viscosity and fiber concentration and it was compared with that of particle suspensions.
