3 lgLightweight material replaces metals and glass to lower the cost of satellitesFAIRFAX, Va., Aug 25, 2008 (BUSINESS WIRE) -- ManTech International Corporation (Nasdaq:MANT) announced today that its Colorless Organic/Inorganic Nanocomposite (CORIN™) transparent polyimide film, used in space and electronics applications, has been recognized by R&D Magazine as one of the top 100 most innovative and technologically significant new products of the year. Called the "Oscars of Invention" by the Chicago Tribune, the R&D 100 awards are given annually to the technologies that have the potential to greatly affect further scientific discovery, human life, and society. Previous award winners include fax machines, ATMs and HDTV. 

ManTech's CORIN™ XLS Polyimide is a colorless, sprayable polyimide nanocomposite that is clear, resistant to radiation and atomic oxygen erosion, and utilizes POSS(R) technology from Hybrid Plastics. CORIN™ XLS Polyimide was developed with funding from the Air Force Research Laboratory as a coating for high strength fibers exposed to atomic oxygen and UV degradation in low earth orbit. CORIN™ XLS Polyimide is ideal for use in space applications requiring high optical clarity and durability to atomic oxygen erosion, such as a replacement for glass covers in solar cells. CORIN™ XLS is also used in display and electronics applications requiring high optical clarity and polyimide-grade temperature stability. 

ManTech's CORIN™ XLS Polyimide is part of a family of polymers developed by ManTech that have been used in spacecraft. ManTech's CP1™ Polyimide, a predecessor product to CORIN™ XLS, is a key component of NASA's experimental solar sail, which uses sunlight to propel vehicles through space, much the same way the wind pushes a sailboat through water. The 100 square foot sail is packed inside the NASA NanoSail-D satellite. ManTech engineers also helped to design the NASA NanoSail-D satellite. 

"We are honored to be named an R&D 100 Award recipient," said the CORIN™ group leader, Garrett Poe, Ph.D., ManTech International Corporation. "Since satellites cost approximately $10,000 per kilogram launch weight, a huge portion of the satellite's cost is tied up in the fuel used to launch the satellite. We recognized the importance of replacing heavy portions of the satellite -- such as metals in support structures and glass in the photovoltaic arrays -- with lightweight replacements to lower the launch weight and therefore lower the overall satellite cost," he said. 

"We designed the CORIN™ technology from the ground up," said Brandon Farmer, Ph.D., ManTech International Corporation. "We recognized the importance of producing a polyimide coating that exhibits the properties we were seeking, and also the importance of producing the coating resins in multi-ton quantities without needing to design a new production plant around the product. CORIN™ XLS fits perfectly into our existing production line of high performance polyimides." 

Traditional polyimide films exhibit high temperature stability but require high curing temperatures, are yellow/orange colored, and rapidly degrade upon exposure to atomic oxygen. ManTech's CORIN™ XLS Polyimide offers temperature stability common to most polyimides, but adds high optical clarity, room temperature cure, and unmatched resistance to degradation from atomic oxygen and anisotropic plasma etching.

The first R&D 100 Awards were given in 1963. Many entries over the years have become household names, including Polacolor film (1963), the flashcube (1965), the automated teller machine (1973), the halogen lamp (1974), the fax machine (1975), the liquid crystal display (1980), the printer (1986), the Kodak Photo CD (1991), the Nicoderm anti-smoking patch (1992), Taxol anticancer drug (1993), lab on a chip (1996), and HDTV (1998). 

One hundred winners that exemplify the best new technologies were chosen from an international pool of contestants from universities, private corporations, and government labs. Winners of the 2008 R&D 100 Awards appear in the September issue of R&D magazine.
