摘要：
Threshold tear strength of unfilled and filled Natural Rubber (NR) and Styrene‐butadiene Rubber (SBR) vulcanizates has been determined. Carbon black (N‐220, N‐375, N‐330, N‐550, and N‐660) and china clay are used as fillers. Threshold tear strength varies from 80 J/m2 to 1200 J/m2. Threshold tear strength is found to be dependent on filler loading, nature of filler, and small strain modulus. The results are explained with the help of strain energy density, tear tip diameter, and the excess energy required to stress the many bonds before breaking one of them.
