Zusammenfassung:Nanocomposites of well-dispersed Al 2 O 3 nanoparticles in acrylonitrile-butadiene-styrene (ABS) matrix were prepared via injection molding. Effects of the percentage of Al 2 O 3 nanoparticles and injection molding process parameters on the mechanical and thermal properties of nanocomposites were studied. X-Ray powder diffraction (XRD) and scanning electron microscopy (SEM) showed that a homogeneous dispersion was achieved with 3% nanoparticles loading. Thermal analyses showed that the ABS/Al 2 O 3 nanocomposites exhibited slightly enhanced degradation behavior when compared with neat ABS. Tensile tests and density measurements revealed that the specific strength and specific stiffness of ABS/Al 2 O 3 nanocomposites were significantly superior to those of neat ABS. Impact tests showed that the addition of Al 2 O 3 nanoparticles to an ABS matrix significantly decreased the impact strength of the nanocomposites. Analysis of variance demonstrated that the percentage of Al 2 O 3 nanoparticles is the dominant variable affecting mechanical properties of ABS/Al 2 O 3 nanocomposites. The effects of injection molding process parameters were statistically insignificant which imply more flexibility on selecting the injection molding processing conditions.
