Properties of thermoplastic composite from Araucaria hunstenii / Ronald Peter Jipiu

The research has been done to study about the properties of thermoplastic composite from Araucaria hunstenii. The test for bending, tensile and thickness swelling and water absorption been done for make sure Araucaria is more suitable in making thermoplastic composite. The making of thermoplastic composite from Araucaria is followed from 5%, 10%, and 15% of Araucaria wood fiber. The result showed that 10% of wood fibers of Araucaria are suitable. This because from bending test showed that 10% of wood fiber is very strength compared to 5% and 15%. Using more polypropylene (PP) can give chance to the fiber bound each other with PP. Otherwise, using MAPP as a coupling agent may increase the strength of the thermoplastic. Generally the suitable percentage fillers is 10% mixed with PP.
