| Abstract: | This work was aimed at studying the effect of various processing parameters on mechanical properties of resulting microcellular injection molded polyethersulfone(PES) based on a design of experiments(DOE) matrices.The microcellular structures of the molded samples were investigated using scanning electron microscope(SEM).SEM micrographs show that cell morphologies vary from surface to core due to the cooling and shearing.A statistical design analysis was used to identify the optimal processing conditions fo... |
