Abstract
The effects of density and cell size on the impact behavior of microcellular polycarbonate (PC) were investigated. A flexed-beam Izod impact test was conducted and the impact strength was observed to improve over the virgin polycarbonate’s impact strength for foam relative densities of 60% and above. In terms of cell size, the impact strength increased with increasing cell size. The impact strength of these foams appears to be a strong function of both density and cell size.
