Self-Healing Aluminum Metal Matrix Composite (MMC)

"Fatigue endurance is vital for the airworthiness of civilian and military aircraft, as well as long-duration flights and deep space missions. " NASA has developed a new metal matrix composite that can shield a structure from massive fatigue cracks that occur during its service life. Both shape memory alloy reinforcements and some low-melting phase components are included in the MMC, which will effectively glue the crack edges back together and flow material into the crack's gap for a high strength repair. The new material allows for the repair of fatigue cracks without the use of additional products or human contact.

Continuous Fiber Composite for Use in Gears

"Innovators at NASA's Glenn Research Center have invented a breakthrough way of adapting strong yet lightweight carbon fiber composite material to produce complex shapes, such as specialty components for drive systems. " Fiber composites can be used to produce flaws in complex shapes, such as a tendency toward weakness and exhaustion at the fiber ends. Glenn's invention introduces the benefits of carbon fiber composites to a broad range of new uses.

Oculometric Testing for Detecting/Characterizing Mild Neural Impairment

"Scientists at NASA have created and validated a fast, non-invasive, eye-movement-based testing device to assess neural health in a variety of brain regions. " The technology employs a 5-minute behavioral tracking task consisting of random step-ramp radial target motion to capture numerous aspects of neural responses to dynamic visual stimuli, such as pursuit launch, steady-state tracking, speed control, pupil response monitoring, and eccentric gaze holding.

Carbon Fiber-Carbon Nanotube Yarn Hybrid Reinforcement

"Innovators at the NASA Glenn Research Center have developed a toughened hybrid reinforcement fiber made from carbon fiber and carbon nanotube yarn for use in polymer matrix composites. " The latest NASA carbon fiber-CNT yarn hybrid material combines excellent toughness and durability for reinforcing PMC materials while also addressing issues encountered with new hybrid reinforcements such as rubber, thermoplastics, and aramids.

Fiber Optic Sensing Technologies

Companies that provide sensing services for monitoring structures and asset management of storage tanks have the opportunity to extend their product line to include unprecedented capabilities. "NASA's Armstrong Flight Research Center is assisting companies in establishing a unique opportunity for monitoring structures and asset management of storage tanks. "FOSS can also monitor a tank's interior, including quantities, temperatures, and stratification.

Crack Image Quality Indicator (CIQI)

"Thus, a demonstration of crack detection with a specific crack demonstration device is conducted to determine the likelihood of detection," says the author. An ideal crack demonstration system would conform to the alloy type, shape, thickness, and likely crack morphology of the components to be tested. Using an inexpensive crack verification kit that accurately portrays crack-like discontinuities for several metal components will facilitate safe crack POD demonstrations while saving time over users' ability to produce their own fatigue crack specimens.
