Prepreg Mixtures and Their Components

AH peak intensities in j/g versus the temperature associated with maximum peak intensity d 4 component mixtures of TGDDM/DDS/DGOP/BF3 NHiC2H5 epoxies and commer 934 prepreg 

From these DSC studies together with our NMR observations from Section 3.3 we conclude (i) the peak is associated with BF3 NH2C2H5 catalyzed DDS-TGDDM impurity reactions (ii) the y peak is associated BF3 NH2C2H5 and monofluroborate catalyses of the cure reactions and (iii) the p peak is associated BF4 NH3 C2H5 cationic catalyses of the cure reactions.
