Abstract:

We have created and tested several sensors one is PANIMWCNT composite a second was a polyurethaneBuckypaper composite and a third was a MWCNTDYADMWCNT composite. The first sensor was a continuation of the research work we have carried on in the past 2 years. The second was a decision to see if the polyurethane can be used to modify the Buckypaper sensor we had investigated in our previous ARO grant. The third was an outcome of the results that we had obtained from the other two sensors. In our 2013-14 progress report we had reported on the preparation and characterization of the polyanilineMWCNT PANIMWCNT and PolyurethaneZnOMWCNT PUZnOMWCNT nanocomposite films. Also discussed in the report were the vibration aspects that needed to be addressed, namely cantilever beam vibrations that were representative of the main barrel of a tank or structural health monitoring, for example. We have been working on determining the proper shape of the sensor and its placement in order to achieve the goals of the grant, namely to maintain a sensor that has linear properties with applied load yet introduce more damping into the sensor than previously existed with the MWCNT buckypaper. Though the grant ended in May, 2015, we plan to continue to work on the control aspect, and, if allowed, we plan to report results to ARO.
