Field Responsive Materials are materials that react to stimuli in the environment by a reversible change in their properties. Shear-thickening Fluids (STF) can be considered Field Responsive Materials due to their change from fluid to solid-like properties when exposed to high strain rates and their ability to revert back to a liquid when the high strain rates are ceased. When STF are incorporated into sandwich structures as an interlaminate layer they can be used as a coupling/decoupling agent between the other sections of the sandwich structure. At low strain rates the STF will decouple the sandwich structure and also act as a dampening device in the structure. At high strain rates the structure will be coupled by the STF making the structure act as a single component. My current research focus is on tuning the STF to obtain specific field responsive characteristics and the incorporation of STF materials into composite and structural design software.
