Development of Nano-Composite Structures with Enhanced Thermo-Mechanical Properties, Damping and Self-Sensing Capabilities

2012-2017

This project aims to develop composite material and structural fabrication and characterization involving synthesizing nano-structured components into the composite material. Specific aim is to incorporate carbon nanotubes and nanoparticles of metals and carbides, ferroelectric and ferromagnetic materials and embedding them in composite fiber, fabric and laminate form and characterize and design such nanocomposite for improved thermo-mechanical, damping and self-sensing properties. Electro-thermomechanical properties of nano-composite laminate structures will be quantified, and nano-strain sensors will be packaged along with required calibration. The work packages include setting up new manufacturing processes and methods, develop analytical schemes for evaluating material response and optimization of nanocomposite for multifunctional property enhancement.
