AbstractThe recent development of AFR-PE-4 polyimide composites has increased the high-temperature performance of large jet engine structures. To take full advantage of these "new" composite systems, high-temperature adhesives are needed to bond these components to other structures. Current F135 and F136 engine systems slated for the Joint Strike Fighter (JSF) require high-temperature adhesives that are formulated to provide service temperatures in excess of 316ºC (600ºF) for up to 1,000 hours of operation while retaining a 1,000 psi lap shear strength. Applications for "film" adhesives include honeycomb bonding and stiffening structures, while "paste" adhesives include dams, bonding of fasteners, and gap filler. The overall goal of the program is to formulate addition-cured polyimide resins and study the impact of chemical structure on high temperature properties, adhesion, and joint durability. Maverick will evaluate addition-cured polyimide resin chemistries with the goal of developing the "next-generation" high-temperature adhesive technology for AFR-PE-4 composite components. Maverick also plans to team with Akron Polymer Systems to formulate "reactive diluents," and to work with Adherent Technologies to develop "primer" technology which will "chemically couple" the substrate to the adhesive. This unique collaboration will be key towards the successful development of a high-temperature adhesive system.
