Effective viscoelastic properties of short-fiber reinforced composites

The paper focuses on the calculation of the effective viscoelastic properties of a short fiber reinforced composite. The orientation distribution of the fibers is described by a scatter parameter, varying from perfectly aligned fibers to randomly oriented ones. Both matrix and fibers are assumed to be isotropic.The viscoelastic behavior is described using fraction-exponential operators of Scott Blair–Rabotnov. Results are obtained in closed form.
