Abstract
The aerospace industry is currently making extensive use of both structural adhesives and composite materials in aircraft and space vehicle construction. Within the past decade, there has been a growing requirement for adhesives and composites capable of withstanding temperatures in excess of 150°C for both short- and long-term applications. Although polymers offering such capabilities have been commercially available for many years, in numerous cases adverse processing characteristics have severely restricted their acceptance. As a result, substantial efforts have been made to develop high temperature resistant polymers having considerably improved processing characteristics. In this paper, a critical assessment is given of the use of high-temperature polymers in both adhesive and composite applications with particular emphasis on some of the newer, more easily processed types which are, or will probably be, commercially acceptable.
