• Abstract:
  The flammability, thermomechanical properties, and fire response of the diglycidylether of 1,1-dichloro-2,2-bis(4- hydroxyphenyl)ethylene (DGEBC) cured with several hardeners were examined and compared to diglycidylether of bisphenol-A (DGEBA) systems. The DGEBC and DGEBA were cured with (1) triethylenetetramine, (2) methylenedianiline, (3) the parent phenol (BPC or BPA), (4) catalytic amounts of (2-ethyl-4-methylimidazole) (EMI-24), and (5) the dicyanate of bisphenol-C. Cured samples were measured for strength, modulus, flame resistance (limiting oxygen index (LOI), UL-94 V), flaming heat release rate, and heat release capacity. The mechanical properties of the DGEBC and DGEBA systems were equivalent but the DGEBC systems exhibited superior flame resistance and 50% lower heat release rate and heat release capacity than the corresponding DGEBA system. The DGEBC cured with methylenedianiline had an LOI of 30-31, exhibited UL 94 V-0/5V behavior and easily passed the Federal Aviation Administration heat release requirement Federal Aviation Regulation 25.853 (a-1) as a single-ply glass fabric lamina.
