Abstract

Polypropylene is widely used in the plastic industry regarding of flexibility polymer properties. Natural fibre coal ash (CA) is used as an essential matrix material for a polypropylene (PP) with help of 1 wt% of stearic acid (SA) coupling agent treated of polypropylene by utilizing literature based on the formulation in search for flexural properties. The primary objective of this research study is to evaluate and determine the strength and limit of polypropylene with coal ash based on flexural strength and modulus in order to finding the appropriate formulation of compound. Coal ash was left 24 hours around 30°C - 40°C to improve compatibility and dry-out moisture content of filler with polypropylene (PP). The compound will undergo crush-press process using hot press machine and crusher machine to ensure the well-mixing of the compound. The specimen cut into dog-bone shape using water jet machine before undergo flexural testing to evaluate and determine a strength and modulus limit. The best compounding formulation of the fabricate compound will be determine and observe with different percentage formulation of polypropylene (PP) and coal ash (CA) which is 100 phg of the polypropylene (PP) and different amount percentage of coal ash (CA) at 1, 2, 5, 7 and 10 from per hundred grams of polypropylene (PP). The morphology of the sample was observed by using optical microscope. Addition of coal ash (CA) filler on polypropylene significantly increase modulus of compound but decreases the strength compound compared to the pure polypropylene. In overall, all the listed research objectives were successfully achieved from this preliminary research.
