Characterization of laccase enzyme-treated kenaf fibre reinforced recycled polypropylene composites

Muhammad Remanul I., . and Mohammad Dalour H. B., . and Arun G., . (2014) Characterization of laccase enzyme-treated kenaf fibre reinforced recycled polypropylene composites. [Proceedings Paper]

Composites were prepared from lignocellulose based kenaf fibre with recycled polypropylene RPP and studied the thermal and mechanical properties. Biological treatment such as Laccase enzyme treatment was used to treat kenaf fibre for the enhancement of interfacial property between fibre and matrix by removal of lignin which holds and binds the cellulose fibre together. Maleic anhydride grafted polypropylene MAPP was used with a ratio of 1:10 as coupling agent to fibre. A twin screw extruder was used to mix the blends and the test specimens for mechanical testing were prepared by an injection molding machine. Various tests of the composites such as tensile melt flow index MF and thermogravimetric analysis TGA were done to evaluate the properties of the composites and compared with the untreated fibre reinforced composites. The best tensile strength TS achieved at 40 loading of fibre and enzymatic treatment of fibre enhanced the TS by 40.

Maleic anhydride grafted polypropylene MAPP was used with a ratio of 1:10 as coupling agent to fibre.
