Thermal Mechanical Analysis Study of Acetylene Terminated Quinoxaline Resins

Abstract

Additional cure effects of TMA (Thermal Mechanical Analysis), experiments are investigated and the results are compared with those from TICA (Torsion Impregnated Cloth Analysis) experiments. The penetration mode results are found to be more consistent and show similar behaviors between known Tg samples and isothermal cure samples. The expansion mode results may have been influenced by the physical aging effects and show different patterns between the two sets of samples. Because of the change in probe movement direction before and after the softening point in the penetration mode experiments, penetration mode results can highlight the additional cure effect more. Comparison with TICA results show, as expected, influence due to scanning rate.
