Rubber Reinforcement

Peel Adhesion of Reinforcing Fabrics Calculator (ASTM D4393)

A mean adhesion figure with wide scatter is a cure problem, not a good bond. Read the deviation before the mean.

Peel force alone does not say where the bond failed. Record the failure mode with the number — adhesive failure at the interface, cohesive failure in the rubber, or fabric rupture — because the same force means entirely different things in each case.
