heal.abstract	A constitutive equation is proposed to describe the steady-state and dynamic rheological properties of fiber-filled viscoelastic media. The constitutive equation used to describe the viscoelastic effects is an integral equation of the K-BKZ type, suitable for polymer solutions and melts. The contribution to the total stress of the composite due to the presence of fibers is accounted for by the extra stress tensor proposed by Dinh and Armstrong for fiber-filled Newtonian liquids. Steady-state predictions of the constitutive equation are compared with experimental measurements of fiber-filled viscoelastic media, namely polypropylene and nylon-66, for different sized fibers and different volume fractions. The constitutive equation predicts qualitatively the rheological properties of fiber-filled viscoelastic media.	en
