Investigating Time Dependent Mechanical Properties of Epoxy with Nano Particles by Using Indentation Tests

Abstract:

The objective of this study was to examine the time dependent mechanical properties of epoxy without/with nano particles composites and how the nano particles in the epoxy affect the relaxation properties of epoxy. Furthermore, viscoelastic constitutive models of epoxy and epoxy composite were established and the corresponding mechanical parameters were obtained by using inverse iterative finite element procedure. The ramp-hold indentation tests were used to investigate the time dependent mechanical properties of epoxy with and without Al2O3 nano particles. Experimental results showed that adding Al2O3 nano particles in to epoxy can reduce the relaxation effect of epoxy.
