Estimation of mechanical (static and dynamic) properties of recycled polypropylene

filled with wood flour (in English)

Polimery 2006, No 7-8, 571


Summary

PP recyclate was filled with two commercial types of wood flour. The effects of the filler content (10 or 20 wt. %) and the dimensions of its particles (70-150 μm or 300-500 μm) on the useful characteristics of the composites obtained were studied. The following features were evaluated: static and dynamic mechanical properties including the ability to energy dissipation as well as creep course. It was found that the filling of recyclate with wood flour influence advantageously the properties investigated and the better results were obtained for the filler of smaller dimensions of particles. Scanning electron microscopy method let find that the presence of the filler investigated, showing good adhesion to polypropylene matrix, caused decrease in PP spherulites dimensions.
