| Abstract: | The annular specimens were prepared with ABS/SBS. By using the custom-made apparatus,the fatigue properties of the annular specimens of ABS/SBS were tested. The morphologic profile of ABS filled with various content SBS were analysed and compared. Meanwhile,by applying different pressure and frequency on the annular specimen,the speed of crack spreading and the shape of profile of ABS/SBS were achieved. Consequently,the influence about the characteristic of filler to the fatigue properties of different proc... |
