 | The Air Force's Integrated High-Payoff Rocket Propulsion Technologies (IHPRPT) Program has established aggressive goals for both improved performance and reduced cost of rocket engines and components. Achieving these goals relies on developing affordable Metal Matrix Composite (MMC) technologies for application to Liquid Rocket Engines (LREs). Efforts are being conducted on three types of MMCs: Aluminum, Copper, and Nickel matrix material systems. Potential applications include turbopump housings, rotating machinery, and high ... |

| Solid and liquid propellant rocket propulsion systems are weigh- and performance - driven machines whose components experience extreme environments. However, the structural integrity of both types of propulsion systems is currently monitored through type testing, labor-intensive x-ray analysis, and other NDE techniques. Smart structures technologies have the potential not only to alleviate some of the maintenance burden of current rocket propulsion systems but also improve the capability of future systems. ... |

| Nylon-6 is an important engineering polymer that, in its fully spherulitic (bulk) form, has many applications in gears, rollers, and other long life cycle components. In 1993, Toyota commercialized a nylon-6/clay nanocomposite out of which it produced the timing belt cover for the 1993 Camry. Although these hybrid nanocomposites show significant improvements in their mechanical response characteristics, including yield strength and heat distortion temperature, little is known about the degradation ... |
