Abstract:

Projected requirements for future high-performance jet engine, missile, and fighter aircraft structures will necessitate extensive use of high temperature structural adhesives. For example, many advanced jet engine and tactical aircraft components will need to perform for hundreds of hours at 700 F 371 C and above. For advanced air-to-air tactical missiles and air-launched stand-off missiles, composite airframe structures capable of maintaining strength for short periods minutes at 1000 F 538 C and above will be needed. Other needs for adhesives capable of performing at high temperatures include bonding of structures for extended range cruise missiles, bonding of specialty materials for stealth applications, and, potentially, joining of aerospace plane structures. Under this program, a comprehensive technical effort was undertaken with the goal of developing high-temperature adhesive systems with inherent processibility and toughness. The approach was to perform a multidisciplinary integrated research effort involving a combination of polymer chemistry, moisture diffusion analysis, and fracture mechanics to tailor, characterize, and qualify tough adhesive systems for bonding to titanium and ferrous alloys. Performance goals for the adhesive systems included the ability to withstand extended duty cycles at high temperature 450 - 700 F or 232 - 371 C while remaining viable under hot-wet and cold-dry conditions.
