Fire resistant cyanate ester-epoxy blends

摘要

The cure chemistry, thermal stability, and fire behavior of a series of fire resistant cyanate ester-epoxy blends were examined. The dicyanate and diepoxide of 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethylene (bisphenol-C, BPC) were combined in various molar ratios and the reaction chemistry was monitored using FT-IR and DSC. Fire behavior of the BPC cyanate-epoxy blends was studied in flaming and nonflaming combustion using fire calorimetry and pyrolysis-combustion flow calorimetry, respectively.
