Abstract

The present work studies the influence of injection molding process conditions over the impact response of Polypropylene Homopolymer  (PPH)  parts.  For  this,  disc  shaped  samples  were  injection-molded  for  a  wide  range  of  mold  (Tm)  and injection (Ti) temperatures values. Impact response was assessed through the falling weight force-displacement curves. As a result, it was found that by decreasing Tm and increasing Ti, test samples show higher impact energies and ductile failure modes. However, it was observed that the studied PPH is under the ductile-fragile transition regime and therefore there is an associated statistical dispersion in the absorbed impact energy values obtained for a given set of processing parameters.
