This work focuses on the development of a numerical mold filling simulation for rotational molding process. In process, dry fiber preform is placed in and impregnated with thermoset matrix under rotation. Additionally, metallic load introduction elements can be inserted into joined co-curing or form-fit, resulting hybrid drive shafts tie rods. The model used to simulate impregnation preform. Ba...

In this work, polypropylene (PP) was foamed via rotational molding using a chemical blowing agent (CBA) based on azodicarbonamide over range of concentration (0 to 0.5% wt.). The samples were then analyzed in terms morphological, thermal and mechanical properties. morphological analysis showed continuous increase the average cell size density with increasing CBA content. Increasing content also...
