The present article describes a methodology for examining the evolution of the properties vs. cure of a complex thermosetting isocyanate/epoxy reactive mixture which reacts through two consecutive but separable reaction regimes. The methodology is based on the use of the torsional braid analysis (TBA) technique and the continuous heating (CHT) and isothermal time—temperature—transformation (TTT) cure diagrams. © 1997 John Wiley & Sons, Inc.
