A study on the effect of mechanical properties and rheologycal behaviour of polyproplene reinforced montmorillonite / Normuhaizah Mohd Zain

This research focused on the mechanical properties of polypropylene (PP) reinforced montmorillonite (MMT). The aim of this research is to determine the mechanical properties of PP/MMT nanocomposite with different concentration (2 wt%, 4 wt%, 6 wt% , 8 wt% and 10 wt%) of MMT. PP and MMT were mix by using Dispersion Mixer. The material was mixed at temperature 190°C. After that, the material was fabricated by using hot press with 190°C for both upper and lower compressor. Mechanical properties of the sample were evaluated by tensile test, impact test, and three-point bending test according to BS EN ISO 527, BS EN 60811 and BS 6319 respectively. From the tensile test, the result obtained shown that the sample of 2wt.% and for impact test shown 6wt.% of clay loading which has the better mechanical properties. The rheological behavior also determined. All the concentration have pseudoplastic, but the better pseudoplastic is 8wt.% of loading clay.
