Empirical Equations for a Study on Strain Rate Sensitivity of Polypropylene Syntactic Foam

Abstract:

The strain rate sensitivity of polypropylene syntactic foams with polymer microballoons in the relative density from 0.5 to 0.8 is studied at the nominal strain rate ranged from 10-1 to 102 s -1. Two equations of matrix materials are introduced to represent the viscoelastic properties, and another two equations are proposed with respect to the parameters of matrix materials to estimate the elastic moduli and yield stresses of polymeric syntactic foams.
