Shape Memory Alloys (SMAs) can be deformed at low temperature and recover their original shape upon heating. New alloys can operate up to ~300 °C, compared to ~80 °C for commercially available alloys. SMAs can be used in adaptive structures, actuators, heat detection devices, medical devices, high-temperature automotive components, aeronautics, and military.
High-Temperature, Low-Melt Resins for Liquid Molding
High-temperature, low-melt imide resins developed for fabrication of automotive components are produced by a solvent-free melt process. They exhibit high glass transition temperatures, low melt viscosities, long pot-life, and can be easily processed by low-cost RTM and vacuum-assisted resin transfer molding. Applications include injection molding of parts, high-temperature engine components, and composite ducts and tubes.
Oil-Free Turbomachinery Technologies
High-temperature solid lubricant materials suitable for foil gas bearings enable the commercialization of a broad array of oil-free gas turbines, compressors, blowers, motors, and other rotating machines that can operate from cryogenic to red-hot temperatures. These tribological coatings and composite powder metallurgy materials have applications in high-temperature steam turbine control valves and other industrial and aerospace applications.
Improved Indium Bump Bonding Using Multi-Step Plasma Process
Indium bump bonding is a standard method of connecting electronic chips to circuit boards. Indium solder “bumps” are deposited over contact pads of both the chip and the board, and then the contact pads are aligned and pressed together to form an electrically conductive bond. However, oxides can form on indium bumps when they are exposed to air. A new multi-step plasma process removes this oxide.
Smart Coating for Corrosion Detection and Protection
A smart, environmentally friendly coating system enables early detection and inhibition of corrosion, and self-healing of mechanical damage without external intervention. The smart coating is based on microcapsules and particles pioneered by NASA. The coating detects corrosion in its early stages, inhibits it, and/or repairs the coating.
Non-Toxic Environmentally Safe Flame Suppressant
This non-toxic, non-ozone-depleting, non-global-warming agent is based on recent success with flame suppressant as a fire suppression agent. The material suppresses a flame by lowering the temperature and reducing the oxygen available for combustion. The water-suppressant technology operates similarly to Halons because it contains a functional group that decomposes to add free radicals to the combustion process.
Layered Composite Insulation
LCI technology can benefit multiple industries that depend on regulation of low temperatures in equipment and products. Improvements in materials, design, and manufacture of the insulation exceed the performance of current multilayered insulation (MLI) or foam insulation products. The insulation may be used for regulating a critical low-temperature environment in industries such as cryogenics, medical, and refrigerated vehicles.
