Torsion impregnated cloth analysis

This allowed the determination of the reduced parameter (T-T ) during cure of the resin under a variety of time-temperature profiles. The dynamic mechanical properties were then estimated as a function of (T-T ). This estimate is compared with the results of torsion impregnated cloth analysis of the curing of the ATS resin. 

The Torsion Impregnated Cloth Analysis (TICA) measurements utilized here were conducted under nitrogen with a Rheometrics Mechanical Spectrometer (RMS) according to the procedures described in the previous paper (7). 

This paper is to describe a series of Torsional Impregnated Cloth Analysis (TICA)(4) experiments where the dynamic mechanical behavior of the resin can be studied during the cure. The resins used in this study are the (3,3 ([3-ethynylphenoxy]-phenyl)-2,2 diphenyl-6,6 biquinoxaline) (5,6) and the 4,4 -bis(3-ethynyl-...
