Abstract

The tangent delta peaks of dynamic mechanical thermal analysis (DMT A) for the blends of epoxies and thermoplastic are analyzed. Effects of blending ratios and the post-curing process on peaks was studied with the help of SEM. Results show that the primary peaks of tangent delta of DMTA mainly response to the segment motions of thermoplastic in a blend and the secondary peaks mainly to that of the DGEBA cured nets. The TGMDA is helpful for the separation of phases in the blends. DGEBA otherwise is helpful for the compatibility. High temperature post-curing prompts the cuing nets construction more perfectly and the phase separation more completely. In the blends the continuous phase mainly consists of a mass of thermoplastic and some TGMDA, DGEBA mainly exists in the dispersed phase.
