| Abstract | ||
| Investigations of fatigue behaviour for five types of rubber were studied according to the international standard specification of Dunlob Company. Reversed tension fatigue tests were performed under room temperature with stress ratio R=-1. The five types of rubber are Natural rubber [RSS,Ribbet smoke sheets] , True of tire , side wall of tire for using NR(Natural rubber , Trade of tire from standard specification of Dunlob company , and side wall of tire from standard specification of Dunlob company . It was found that , the longer fatique life is the trade rubber of tire from standard specification of dunlob company the lowest life is the Natural rubber [RSS] . The mixing between NR and BR caused reduction in fatigue life for natural rubber. Finally relationships were expressed as empirical equations. | ||
