Abstract

The Izod and Charpy impact properties, including V notched and unnotched, of acrylnitrilebutadiene-styrene copolymer (ABS) filled with hollow glass beads (HGB) were measured at room temperature in the present paper, to identify the effect of the HGB contents on the impact fracture behavior of the composites. The mean diameter of the HGB was 70 μm, and the surface of the beads was pretreated with a silane coupling agent. The results showed that both Izod and Charpy (including notched and unnotched) impact strength (σ₁) of the composites decreased quickly when the volume fraction (φ_f) of the HGB was less than 5 %, and then decreased gently with increasing φ_f. Both V-notched Izod and Charpy impact strength are close to each other, especially at low filler concentration. Furthermore, the impact fracture surfaces of the V-notched Izod impact specimens were observed by means of a scanning electron microscope. It was found that there was debonding phenomenon between the beads and the matrix, and the HGB in the ABS matrix was undamaged. In addition, obvious agglomeration phenomenon of the particles in the matrix was not observed.
