Abstract
Mineral fillers namely talc, calcium carbonate, mica, glass and carbon fibres
are common fillers used in plastic industry that can alter thermoplastic properties. With
the incorporation of fillers, significant outcome can be observed especially in the
mechanical properties of polymer composites produced apart from its rigidity and
resistance to temperature. Properties of single and hybrid fillers filled polypropylene
(PP) composites were studied in this research work. Mineral fillers such as talc, mica
and calcium carbonate (CaCO3) were incorporated into PP composites. Realising the
advantage of each mineral filler and the effect of hybrid fillers, CaCO3/Talc (CC/T) and
CaCO3/Mica (CC/M) at 40 wt% were investigated. Generally, the results demonstrated
that CC/M has higher tensile modulus than CC/T and both hybrids composites did not
give significant effect on the tensile strength. Thermogravimetric analysis (TGA) results
revealed that CC/M increased thermal stability of PP composites when compared to
CC/T. Flammability testing on PP hybrid composites was carried out where lower
burning rate indicates better flammability. From the results, it shows that CC/M system
have better flammability compared to CC/T system.
