Abstract
Acetone-formaldehyde (AF) resin having dihydroxy functionality (-CH2OH) was prepared and polycondensed with 1,5-dihydrxynaphthalene (DN) at equimolar. Three component interpenetrating polymer networks (IPNs) were prepared from actone-formaldehyde-1,5- dihydrxynaphthalene (AF-DN) resin, diglycidylether of bisphenol-A (DGEBA) and methyl methacrylate (MMA) monomer. Thermal behavior of IPNs was studied by a differential scanning calorimeter (DSC) and unreinforced cured samples of IPNs were subjected to thermogravimetric analysis (TGA). Glass fiber reinforced composites (GFRC) based on such IPNs have been prepared and characterized by chemical, mechanical and electrical properties.
