| Abstract: | Colored epoxy resin containing azo moiety was synthesized by reaction between epichlorohydrin and bis-azodiol, which was synthesized by coupling bisphenol-A with aromatic amine. Colored epoxy resin was characterized by epoxy equivalent weight, IR spectra, Viscosity and UV visible spectroscopy. The curing of colored epoxy resin and DGEBA were characterized by differential scanning calorimetry (DSC). The thermal stability of cured products was characterized by thermogr avimetric analysis (TGA). The cured products have good thermal stability. Several glass fiber epoxy composites were fabricated and their mechanical properties, electrical properties and chemical resistance were studied. |
