Cross linked rubber stress strain curve
WebIn our study, cross-linking of ENR and NR with dicumyl peroxide and sulfur to provide realistic models of commercial rubber formulations is described, and a cross-linking density of 5 × 10 –5 mol cm –3 in sulfur-cured ENR is demonstrated to achieve a healing efficiency of 143% for the tensile strength. WebFigure 1 shows stress-strain curves of rubber composites with reinforcement of N330 (Figure 1 (a)) and N220 (Figure 1 (b)), respectively. During the initial portion of the tensile testing, the ...
