On fabrication and characteristics of injection molded ABS/Al2O3 nanocomposites
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 st...

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
