Cyclohexanone-formaldehyde (CHF) resin was brominated and the brominated CHF (BCHF) was then reacted with excess hydrazine derivatives. The hydrazinated CHF resin designated as HCHFs (i.e. modified ketone resin) were characterized and then applied as epoxy resin curing agents. Thus the curing of commercial epoxy resin namely Diglycidyl Ether of Bisphenol-A (DGEBA) by HCHFs was monitored by differential scanning calorimetric (DSC) and from the DSC scan the glass fibre reinforced composites of DGEBA-HCHF systems were prepared and characterized by chemical resistivity and mechanical properties.
