The Time-Temperature-Transformation (TTT) State Diagram and Its Role in Determining Structure/Property Relationships in Thermosetting Systems.

reportActive / Technical Report | Accession Number: ADA096127 | Open PDF

Abstract:

A generalized time-temperature-transformation TTT state diagram for the thermosetting process is presented in which the four physical states encountered i.e., liquid, rubber, ungelled glass and gelled glass are related to the time and temperature of cure. Gelation and vitrification, as a consequence of quenching morphological development and chemical conversion respectively, are discussed with respect to control of material properties. Author
