TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
While much attention is necessarily focused on the evaluation and certification of the materials and processes involved in adhesive bonding, development is still needed in decreasing the cost, time, and complexity of the current repair concepts. A material and processing system is needed that allows the design, infusion, and cure of composite repairs without the current roadblocks imposed by ovens, autoclaves, and expensive tooling. VARTM processing of custom repairs allows freedom in design and minimizes the specialized tooling required for patches and straps that are prefabricated apart from the structures needing repair. CRG's no-oven, no-autoclave (NONA) composite processing technology enables the fabrication of high-performance composite parts without the limitations imposed by autoclaves and ovens. NASA originally funded CRG to develop the materials and processes for the manufacture of large, single-piece space launch structures. Building on that activity, CRG proposes NONA repair of composite structures. In this concept, NONA resin is introduced to a scarfed surface and dry fiber via VARTM processing and undergoes complete cure without additional heat input. NONA offers the opportunity to repair PMC structures on-site without the use of large capital equipment. The University of Dayton Research Institute will conduct the scarfing and evaluation of test materials. The resin consists of common aerospace epoxy components, but it is formulated to achieve complete cure in a matter of hours without additional heat input. The two-part epoxy system uses its own chemical energy to propel itself through a complete cure. It provides good strength, chemical resistance, and thermal performance up to 350 deg. F. CRG envisions a mobile fleet of NONA composite technicians that can perform repair activities at manufacturing sites around the world, restoring functionality to damaged structures and tools, minimizing impact on plant operations and production.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Supporting NASA's Kennedy and Johnson Space Centers, this project's technologies directly address requirements for simplified but effective repair techniques for Space Launch System composite fairings, skirts, and tanks. This project's technologies offer reduced infrastructure footprint, reduced time for preparation, and reduced time for complete repair to enable minimal delays in vehicle launch if a repair is deemed necessary.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Government systems that would derive the same benefits would include helicopters, UAVs, engine fan structures, and fighter and cargo aircraft in need of quick repair operated by the U.S. Army, Navy, and Air Force and foreign governments. This technology's attributes for rapid, "in-field" repair should yield a high potential for private sector commercialization for commercial space launch vehicles by SpaceX, United Launch Alliance, or Orbital ATK; and use for a wide variety of aerospace MRO (maintenance, repair, and overhaul) organizations who need a rapid repair for time critical AOG (aircraft on ground) situations. Two specific MRO organizations that CRG and NONA Composites have a relationship with are Airborne (Middletown, OH), specializing in B757 and B767 cargo aircraft repair, and Applied Composites Engineering (Indianapolis, IN), specializing in radome repair.
