초록
The tension-temperature coefficient and the isothermal stress-strain behavior and thermal behavior have been measured for dicumylperoxide crosslinked TOR rubber. The elastic equation of state has been used in order to convent the thermodynamic data obtained at constant pressure into the corresponding data at constant volume. From the experimental results, the existence of the inversion point in the stress-temperature curves is shown to be due solely to ordinary volume thermal expansion and may be eliminated by correcting this thermal expansion. And at low extension ratio, linear thermal expansion coefficient is shown to be positive value because the component of volume expansion as internal energy contribution term is larger than that of thermoelastic retractive force as entropy contribution term. But at the higher extension ratio, the component of thermolastic retractive force become larger than that of volume expansion.
