碩士 === 崑山科技大學 === 材料工程研究所 === 107 === The 0.5 wt% silica nanoparticles and different amounts of α-Cellulose short fiber were incorporated into the polypropylene (PP) matrix to obtain the PP/SiO2/α-Cellulose composites using a twin-screw extruder. The performances of the PP composites were estimated. It is showed that the ultimate tensile strength (UTS) and Elongation at break of the PP/SiO2/α-Cellulose composites increased, compared with those of the neat PP. The SEM image showed the fiber pull-out phenomenon on the fractured cross-section of tensile test specimens which the α-Cellulose short fiber was incorporated. Moreover, the thermal degradation temperature for 5 wt% weight loss of the PP/SiO2/α-Cellulose composites could increase about 130oC as compared to that of the neat PP.
