Fire-resistant cyanate ester-epoxy blends

The cure chemistry, thermal stability and fire behaviour 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 Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The fire behaviour of the BPC cyanate-epoxy blends was studied in flaming and non-flaming combustion, using OSU calorimetry and pyrolysis-combustion flow calorimetry (PCFC). respectively.
