This test method covers the use of dynamic-mechanical-oscillation instrumentation for gathering and reporting the thermal advancement of cure behavior of thermosetting resin. It may be used for determining the cure properties of both unsupported resins and resins supported on substrates subjected to various oscillatory deformations. This test method is intended to provide a means for determining the cure behavior of supported and unsupported thermosetting resins over a range of temperatures by free vibration as well as resonant and nonresonant forced-vibration techniques, in accordance with Practice D4065. Plots of modulus, tan delta, and damping index as a function of time/temperature are indicative of the thermal advancement or cure characteristics of a resin.
