Abstract
We investigated dynamic mechanical properties in functionally graded (FG) syntactic foams which had graded distribution of Acrylonitrile micro-balloons in epoxy resin matrix. The density distributions in the FG syntactic epoxy foams were graded by floating phenomenon of the micro-balloons in the matrix resin during curing process. Dynamic viscoelastic measurements and compression tests were conducted to evaluate distributions of mechanical properties in the foams. The dynamic viscoelastic measurements revealed that the thermo-viscoelastic properties of the foams were determined by the properties of the epoxy matrix resin. The static and dynamic compression tests provided relations between the mechanical properties: the compressive Youngs modulus and yield stress, and the density in the foams.
