Abstract
The effect of density (relative densities 0.33 to 0.90) on the impact behav ior of microcellular polycarbonate (PC) was investigated. Cell size and foa ming gas content were also considered. Flexed-beam Izod impact tests were c onducted and the impact strength of these foams appears to be a strong func tion of both density and cell size. The impact strength was observed to imp rove over the unprocessed polycarbonate's impact strength for foams with re lative densities of 60 percent and above. In terms of cell size, the impact strength increased with increasing cell size at a given density.
