During my doctoral studies, I executed extensive experiments to characterize the complex interface mechanics in carbon nanotubes (CNTs) grafted carbon fiber reinforced polymer composites. The findings of my research have expanded the knowledge base and understanding on the role of interphase in governing the average mechanical properties of fiber reinforced plastics. Interfacial chemistry, wettability, interface/interphase area, and surface energy are the key parameters that offer us a tool to design the composite materials as per the functional requirements of a particular application. Not only the quasi-static strength but the rate sensitivity of the interphase can be tailored by playing with these control parameters.
Predictive analysis was also carried out to ascertain the effects of CNT grafting on the coupled extension-bending-twisting behavior of laminated composites.
Currently, I am working as Research Associate at Aeronautical Development Establishment, DRDO, Bangalore.
