About

My current research falls under two broad areas viz. (1) synthesis and characterization of nanofiller and natural filler suspended epoxy nano composites and smart materials which can be used not only as adhesives for joining similar/dissimilar materials but also for fabricating laminated composites with reduced anisotropy and (2) computational analysis of mechanical, thermal degradation and fracture behavior of the polymer nanocomposites, adhesives and their joints and laminates, and subsequently correlating with the micro mechanisms affecting fracture and thermal behavior. I am also involved into developing self healing polymer composites and their characterization, which can be used in polymer composites to increase the life. Autonomous healing materials can be obtained by a number of ways like incorporating micro capsules or a vascular networks carrying liquid healing agent in it. The basic idea is to fill cracks with monomers that flow out of the embedded micro capsules or tubes during a damage event and to trigger a polymeric reaction to cure the healing agent thereof. Development and detailed analysis of such kind of capsules can overcome the difficulties faced currently in laminates as well as adhesive joints by enhancing delamination toughness at the interfaces of the fiber and the matrix in case of laminates and substrate and the matrix in case of joints. Since properties of the nanofiller induced composites are largely dependent on the mono dispersion and compatibility of the nanofillers with the base matrix. My research is also focused on enhancement of interfacial interaction between reinforcing material and matrix without sacrificing the rheological properties of the resultant nanocomposites which otherwise would be difficult for industrial production and their implementation. Work is also carried out for developing different nanofiller modified laminates and their joining and enhancing the surface energy of their joints by different surface modification processes. These represent broad interest and use techniques in developing polymer nanocomposites with enhanced mono dispersion, thermo-physical behavior and fracture toughness by understanding degradation kinetics and micro mechanisms involved.
