Abstract
Diglycidyl ether of bisphenol - A (DGEBA) epoxy resin - clay nanocomposites was synthesized with diamino-diphenyl methane (DDM) curing agent. Nanocmposites were synthesized at different curing temperatures (60 degrees C, 80 degrees C, 100 degrees C and 120 degrees C), at various level of clay content in matrix (13% and 5%). The aim of this work is to study the effect of curing temperature on nanocomposite structure and properties. It is observed that property and structure of nanocomposites is governed by curing temperature and clay content in the matrix. Higher curing temperature shows increased mechanical properties over low temperature curing. Maximum increase in tensile properties is observed for 2 wt% nanoclay concentration irrespective of curing condition.
