Abstract
Frictional behaviors of the bisphenol type epoxide resins which were cured with aliphatic α, ω-diamines and have network chains in different concentrations were followed by monitoring the change of frictional coefficient in the glassy, transition and rubbery regions of the system.
In the glassy region, a constant value of frictional coefficient was obtained in spite of the variation in contact pressure. A good correlation was observed between the frictional coefficient and the concentration of network chains or modulus of the cured system.
In the transition region, the maximum value of frictional coefficient was observed at the glass transition temperature. A good correlation was observed between the maximum values of frictional coefficient and the damping of cured resins.
In the rubbery region, a constant value of frictional coefficient was observed in spite of variation in contact pressure. A good correlation was observed between the frictional coefficient and the concentration of network chains.
