Dynamic Mechanical Properties of Filled Polymers,

Abstract

Rigid fillers increase the dynamic elastic moduli and often the mechanical damping when incorporated into a polymer. In some cases, fillers also increase the temperature at which damping is a maximum, and the damping peak may be broadened. The effects of filler concentration, particle agglomeration, and ratio of particle modulus to polymer modulus on dynamic mechanical properties are reviewed. The reasons why moduli are lower than predicted and why the relative moduli are temperature dependent are explained. In polyblends and polymers containing soft fillers, the modulus is lowered by the filler, and phase inversion can occur. A theory of phase inversion is described. (Author)
