This proposal addresses the development and use of lightweight, low thermal-capacity reformable tooling materials for high-temperature composite processing evaluation, parts prototyping, trial production and full-rate production of PMC engine components. The weight-saving promise of high-temperature polymer matrix composites (PMCs) for engine components is offset by the very high costs of parts ma ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

CompuTherm, LLC proposes to develop WinChem, an innovative and user-friendly computer program integrated with a thermodynamic database, to provide a significant new capability to rapidly determine chemical equilibrium necessary to evaluate the stability of high-temperature structural materials under corrosive (generally oxidative) conditions. The lack of this capability has been an obstacle to th ...

CompuTherm, LLC in collaboration with Oak Ridge National Laboratory proposes to develop a modeling tool that can be used to understand the effect of Ti, Zr, and Hf addition on the improvement of ductility of the (Mo) phase in the Mo-Si-B system. The tool will be developed by integrating thermodynamic modeling with mechanical testing. Thermodynamic descriptions of the Mo-Si-B-X (X=Ti, Zr, Hf) syste ...

The Department of Defense (DoD) is currently seeking strategies to provide efficient and dependable power systems for small unmanned systems. The engines must run on heavy fuel, be lightweight, produce high horsepower and have the ability to run in extreme environmental conditions. New technologies are needed to meet the DoD’s requirements for small, heavy-fuel engines, including injection syste ...

Current methods for the covert loading and execution of software typically operate at ring zero or are hypervisor based. Detecting the presence of hidden processes is a cat and mouse game when using traditional kernel-based techniques, and timing analysis and other methods have demonstrated the ability to detect the presence of a hypervisor as well. Modern hardware platforms provide opportunities ...

Ongoing anti-terrorist and counter-insurgency operations in Iraq following the lightning conventional war of spring 2003 highlight the fact that war is seldom as simple or as quickly resolved as we expect-or hope-it to be. Even more importantly, they remind us that no enemy is truly beaten unless and until they accept that they are. Although the U.S. military succeeded in an impressively rapid and ...

Amorphous hydrous ruthenium oxide(Ru02.xH20A) has a specific capacitance at least two times larger than any other known capacitor materials. An object of this proposal is to demostrate the feasibility of producing shock-hardened RuO2. H2O based electrochemical capacitors suitable for use in power sources for advanced weapon system applications. A 25 V, 150 mF shock-hardened electrochemical capa ...

Friction Stir Processing (FSP) has been demonstrated to generate refined microstructures, resulting in improved material properties. This has several areas of application. First, FSP can enhance the formability of the particular alloy of interest. This is especially important for the superplastic forming process, where the use of FSP can be used to create superplastic behavior at high strain r ...

In the Phase I study of Zero Volatile Organic Compounds (VOC) Aircraft Coatings (Contract Number FA8650-07-M-5029), the feasibility to formulate environmentally safe, high performance, dual-cure (UV cure followed by air dry) urethane gloss topcoat as well as conventional fast dry two-component chromate-free epoxy primer, was demonstrated by preliminary results. The 100% solids non-chromate pr ...
