Curing Kinetics Analysis and Properties Researches of Cyanate Composites
Abstract:
The powdery nitrile butadiene rubbers (P-NBRs) are employed to improve the comprehensive properties of the bisphenol A dicyanate ester (BADCY). The addition of P-NBRs affecting on the curing kinetics of the composites is analyzed and characterized by gelation test, differential scanning calorimentry (DSC) and Fourier transformed infrared spectroscopy (FTIR). And the contents of P-NBRs affecting on the mechanical and dielectric properties of the P-NBRs/BADCY composites are also investigated. Results show that the addition of P-NBRs has little influence on the cure activation energy. The mechanical properties of the P-NBRs/BADCY composites are optimal with 5 wt% P-NBRs. The dielectric constant values of the P-NBRs/BADCY composites are increased with the increasing addition of P-NBRs.
