摘要
Increases in dynamic strain amplitude (DSA) causes changes in the dynamic mechanical properties of high abrasion furnace (HAF) carbon black filled polyacrylic acid (PAA) and epoxidised natural rubber (ENR) blends. But the changes are more prominent in comparison to conventional rubber vulcanizates. It is believed that crosslinking between PAA and ENR in the presence of carbon black results in the formation of a network-induced-agglomerate superstructure which, however, breaks down on the application of dynamic strain.
