Abstract

Epoxy/nanoclay composites based on diglycidyl ether of bisphenol-A was cured by isophoronediamine and different weight percents of organically modified montmorillonite (O-MMT) clay (3, 5 and 7 wt%). Epoxy/nanoclay composites were characterized by different techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. The compressive strength of the epoxy/nanoclay composite with a 3 wt% of O-MMT was higher than that of pure epoxy and other composites. Thermogravimetric analysis showed no change in the thermal behaviour of the cured epoxy after incorporation of O-MMT.
