To Investigate Thermal and Mechanical Properties of Binary Epoxy Nanocomposites

Abstract

Sodium Dodecyl Sulphate (DDS) intercalated magnesium aluminium layered double hydroxide (Mg Al SDS LDHs) were synthesized and used as additives for the preparation of epoxy nanocomposites. The properties of the additives and their epoxy nano-composites were characterized by X-ray diffractometer (XRD), SEM, UTM and TGA. The Mg-Al SDS LDH additions into the epoxy resin, which was shown by a stable improvement of the thermal properties of the nanocomposites as to comparison to virgin epoxy resin. Due to the presence of Mg-Al SDS LDH, the epoxy nano-composites developed a rigid and dense upper layer, with stable charring, which prevented the escape of the decomposed flammable volatiles and protected the lower layer of the nanocomposites from further decomposition. The mechanical strength of these composites was also assessed.
