The adhesion between rubber and short glass or asbestos fibers has been studied using restricted equilibrium swelling measurements. It has been demonstrated that with improved adhesion between short fiber and rubber,\documentclass{article}\pagestyle{empty}\begin{document}$ V_r = \left( {\frac{{V_I - V_F }}{{V_I }}} \right) $\end{document} decreases by more than 0.04 units, where V I and V F respectively are the volume fractions of rubber in the dry and swollen samples. Goodrich compression fatigue and tensile measurements have been used to substantiate the adhesion‐promoting role of bonding agents. The preferential role of silica over black as an adhesion promoter has been questioned. The effect of fiber orientation in controlling the anisotropy of restricted swelling has also been demonstrated.
