| Summary: | New composites based on polypropylene as polymer matrix reinforced rice husk have been developed. The improvement of
mechanical and thermal properties can be achieved by the addition of inorganic filler namely titanium dioxide (TiO ). In this
work, two series of composites formulation of polypropylene reinforced rice husk with and without TiO incorporation were
prepared. The composite was firstly melt compounding with a twin screw extruder and then were injection molded.
Mechanical tests were applied to obtain tensile strength, Young's modulus and elongation at break. Morphology of fractured
surface of the composites also was observed using Scanning Electron Microscope as well as thermal properties was analyzed by
Thermogravimetric Analysis (TGA). The results showed that the composites with an inclusion of inorganic filler TiO gave
better mechanical properties than the composites without inclusion of TiO and pure PP. The maximum value of tensile
strength which was 41.2 MPa represented by the composites formulation of PP/RH-10 wt%/TiO . Generally, Young's modulus

of PP/RH-40 wt%/TiO composites showed increment which was 1086.16 MPa and 635.48 MPa higher than that of pure PP
and PP/RH. Elongation at break decreased in PP/RH/TiO as compared to PP/RH composites. Scanning electron microscope
(SEM) micrographs show improved interaction between RH and PP matrix by having a good interfacial adhesion as a result of
TiO inclusion in PP/RH composites. Thermogravimetric analysis (TGA) indicated that thermal stability of PP/RH/TiO
composite was increased as compared to pure PP and PP/RH composites. Incorporation of inorganic filler TiO into PP/RH
significantly enhanced mechanical properties and thermal stabilities of the green hybrid PP/RH/TiO composites. |
