Abstract

In this study we assessed the fracture toughness, K_Ic, and the impact resistance of syntactic foam reinforced with glass microspheres of different densities and polymer binder as a function of microstructures. The results showed that both K_Ic and the linear elastic energy release rate, G_Ic, increased with increasing volume fraction of glass microspheres, and the increase was higher for microspheres possessing a lower density. The impact resistance of syntactic foam decreased with the inclusion of hollow microspheres.
