Abstract

The mechanical properties and morphology of the composites of nylon 6, acrylonitrilebutadiene-styrene (ABS) rubber, and nano-SiO2 particles were examined as a function of the nano-SiO2 content. A mixture with separation and encapsulation microstructures existed in the nylon 6/ABS/nano-SiO2 at lower nano-SiO2 content, and ABS and nano-SiO2 improved the toughness synergistically, while obvious agglomeration appeared at higher nano-SiO2 content and the impact strength decreased. Moreover, the addition of nano-SiO2 particles also affected the dispersion of the rubber phase, resulting in the appearance of smaller rubber particles. The deformation and toughening mechanisms of the composites were also investigated; they resulted from rubber voiding, crack forking, and plastic deformation of the matrix.
