Talc or Calcium Carbonate (CaCO3) reinforced Polypropylene hybrid composites were prepared by melt blending
method using hot press at 176°C. Thermal and mechanical properties of the hybrid composites were investigated by
using Thermo gravimetric/Differential Thermal (TGA/DTA) analyzer and Universal Testing Machine (UTM) machine
respectively and compared with those of pure PP and also with each other of single filler filled matrix. Increase in
flexural and tensile modulus and better thermal stability were attained for hybrid composites at 5% of the filler (Talc
or Calcium Carbonate) exfoliation. In addition, water absorption and biological degradation through soil burial test
were also successfully done by increasing loading percentages of two fillers.
