Enhanced interfacial properties of graphene oxide incorporated carbon fiber reinforced epoxy nanocomposite: a systematic thermal properties investigation

Abstracts

In this study influence of the graphene oxide (GO) inclusion on the thermal properties of carbon fiber reinforced polymer (CFRP) hybrid composite is reported. Different wt% content of GO used for development of epoxy matrix and CFRP hybrid composite was prepared using compression moulding process. The nanocomposites were characterized by various techniques viz. DMA, DSC, TMA, and TGA. It is observed that in GO-epoxy resin composites, storage and loss modulus reached maximum for 0.3 wt% of GO. The storage modulus of CFRP hybrid composite is achieved almost double with the addition of 0.3 wt% of GO. The glass transition temperature (T_g) calculated from DMA and TMA of GO incorporated CFRP hybrid composites demonstrated the enhancement in T_g by 4 °C and 12 °C respectively over to CFRP composites at 0.3 wt% GO. This improvement at GO loading is because of constraint effect of GO sheets on the polymer chain mobility in the composite.
