The objective of this proposed Phase II work is to develop a production method for manufacturing rolled plates of a high-strength aircraft aluminum alloy (7075) with high SCC (stress corrosion cracking) resistance. The corrosion resistance is to be improved without a loss in tensile strength. The basic operational processing procedure is to produce aluminum alloy plate through roll bonding of a co ...

Physical Sciences, Inc. (PSI) has demonstrated that electroactive polymer coatings (EAP) may be applied to the surface of the cathode materials for lithium-ion batteries to protect against catastrophic cell failure. These EAP coatings form an electrochemical"switch"that can prevent catastrophic failure in lithium-ion batteries by reversibly changing from a conductor to an insulator on overdischarg ...

Micro Air Vehicles (MAV) have emerged as a critical need for the U.S. Air Force. MAVs are envisioned to conduct a variety of indoor and outdoor reconnaissance missions and must be highly mobile and man-portable. Furthermore, many of the envisioned missions for MAVs require significant endurance. Unfortunately, current state-of-the-art lithium-ion batteries are not capable of providing sufficient e ...

Through this research effort, DSR is developing test equipment that can be used by the Air Force to investigate inert and live explosive material properties through a variety of different pressure and temperature environments. Strain-rate levels are adjustable and will vary between 10-5-10-2 s-1 depending upon the stiffness and strength of the test material. 25.4-mm-diameter specimens with lengt ...

The purpose of this project is to develop new language training methods that help guard against language skill decay, and help recover from skill decay when it has occurred. It leverages previous DoD and ONR investments in language learning technology, but it focuses squarely on the language attrition problem. In addition to providing language training that is resistant to decay, it pays particula ...
