Very Rapid Cure Capable Resin and Optimization for Pre-Preg Process Development of Barrier or Isolation Ply Materials Navy SBIR FY2008.2 Sol No.: Navy SBIR FY2008.2 Topic No.: N08-150 Topic Title: Very Rapid Cure Capable Resin and Optimization for Pre-Preg Process Development of Barrier or Isolation Ply Materials Proposal No.: N082-150-0741 Firm: Renegade Materials Corporation 3363 South Tech Blvd Miamisburg, Ohio 45342-0826 Contact: Susan Robitaille Phone: (937) 901-1202 Web Site: renegadematerials.com Abstract: Ultraviolet (UV) cure materials have been used extensively in automotive and industrial applications, for decades. Several high-performance UV-curable resins have shown promise for use in military aircraft applications as a composite layer to restore the galvanic barrier, and also as a machining layer to achieve impossible to net-mold composite dimensional tolerances. It is the goal of this program to evaluate a new UV curing resin technology. This program will determine baseline properties and allow optimization of the UV resin chemistry to achieve high glass transition (Tg) temperatures and a good balance of mechanical properties. The rapidly cured UV composite materials promise to result in significant savings in fabrication time, cost, and repair of aircraft such as the F35 Lightning JSF. The purpose of this SBIR is to combine the expertise of UV cure researchers with that of proven aerospace composite product development leaders - to demonstrate, manufacture, and commercialize a qualified UV-cure Epoxy-Fiberglass prepreg product for transition to this production platform. Benefits: Availability and readiness of modern advanced fighter aircraft is critical to the United States maintaining its military superiority. Fabrication methods that significantly reduce the cycle time for production of military aircraft will enhance of our military advantage. Typical fighter aircraft manufacturing processes for composite materials are slow and expensive and any methods that can be developed to reduce cycle times and cost will add to our military advantage. The current processes used for restoring corrosion protection on F-35 aircraft graphite-composites parts are time-consuming and waste-intensive. UV cure materials can reduce processing costs by eliminating expensive prepreg freezer storage, and labor-intensive autoclave or vacuum-bag/oven curing - vastly reducing the time and cost to complete the restoration process.
