Abstract
Modified Mannich base (EPK-3251) cured epoxy resin of 9,9’-bis(4-hydroxy phenyl)anthrone-10 (EAN) is thermally stable upto 360°C and followed first order decomposition reaction with 52.5% residue at 700°C. Jute and glass composites were prepared by hand lay-up followed by compression molding at 150°C for 4h under 2 bar pressure. Jute-EAN (J-EAN) and glass-EAN (G-EAN) composites showed fairly good mechanical and electrical properties and excellent hydrolytic stability against different alkaline and saline environments. Equilibrium water absorption and diffusivity are affected by nature of electrolytes. Both the composites might be useful for low load bearing housing, electrical and electronic as well as marine applications.
