| Abstract: | The physical relaxation behaviour of vulcanized rubber is described by the conception of relaxational velocity( V SR ). The results showed that using V SR =5 i =1 A iτ ie (-t/τ i) velocity equation is better to reflect stress relaxation behaviur of vulcanized rubber and have influence on relaxation at different temperatures. The V SR is considered more scientifically to describe vulcanization natural rubber of physical relaxation behaviour. |
