Abstract
Methylolated cyclohexanone-formaldehyde resins having different hydroxyl values were reacted respectively with commercial epoxy resins, i.e., diglicidyle ether of bisphenol A and brominated DGEBA. The resultant polyether products were designated as I(a-f) and II(a-f), respectively. All the polyether samples were characterized by elemental analysis, FTIR spectral studies, thermogravemetric analysis and average molecular weight, estimated by vapor pressure osmommetry. The polyether samples were then mixed with appropriate amount of DGEBA epoxy resin, monitored for differential scanning calorimetry, and based on this, the glass fiber-reinforced composites were prepared. All the resultant laminates were characterized by physical and mechanical properties.
