- Abstract
The article discusses the performance of polypropylene (PP) and polypropylene/calcium carbonate (PP/CaCO3) within the context of mechanical vibration injection molding. Special focus is given the dynamic mechanical properties of polymer in vibration techniques including long-time creep, fatigue properties under circulate stress, and stress relaxation. Topics include similarities between the trend of stress-relaxation change and loss angle tangent value change and changes in polymer behavior due to changes in the vibration force field.
