Effect of Montmorillonite Clay Content on the Mechanical and Thermal Properties of Flame Retardant Epoxy Nanocomposites
Keywords:
Epoxy, MMT, Thermal Stability, SEM, Mechanical PropertyAbstract
In the present investigation an effort has been made to develop nanocomposites using epoxy resin as polymer matrix and MMT as reinforcing agent. This study has been conducted because flame-retardant epoxy resin has wide applications in adhesive, coatings and as advanced composites in the aerospace and electronic industries. Nanocomposites have been prepared through melt mixing process. Mechanical Properties of the developed nanocomposites have been evaluated by universal testing machine. Thermal stability has been studied by thermo-gravimetric analyzer. TGA results revealed that there is appreciable improvement in thermal stability due to increase of MMT content in the epoxy resin. It has been also been observed that maximum thermal stability has been achieved with 3 wt % content of MMT in epoxy resin. It has been observed that the limiting oxygen index values has shown remarkable improvement in flame retardant characteristics of the developed nanocomposites. The structure-Property relationship has been established with the help of FTIR. The distribution pattern of the MMT in the epoxy matrix has been studied through XRD. Morphological studies of the developed nanocomposites have been characterised with the aid of scanning electron microscope (SEM). It has been observed that there is excellent improvement in mechanical properties, thermal stability and flame retardant properties due to incorporation of MMT in epoxy matrix.
