Notes:
The chemo-rheological behavior has been elucidated for three high temperature epoxy resins. Constant temperature and shear stress measurements were made on a modified Weissenberg Rheogoniometer. Curing behavior of various temperatures is unified by a time-temperature superposition method. The curing rate of one resin, Ferro E-293, is limited by the chemical reaction. The other resins, 3M PR-286 and PR-288, each have consecutively occurring reactions, both of which are diffusion limited. The chemo-rheological information obtained for these materials is used to model viscosity for compression molding of hand-laidup composites.
