✦ Synopsis

Three micromechanical models for estimating complex viscoelastic moduli in aligned short fiber reinforced three-phase polymer composites have been developed. A number of geometrical and material parameters have been identified. The effects of the fiber aspect ratio, and damping and stiffness properties of fiber, matrix and interphase (a distinctive third phase in between the fibers and the bulk matrix with its own viscoelastic properties) on the composite damping and stiffness are analyzed and discussed.
