Current and Future Aerospace and Elastomer Needs

Elastomers have a wide usage range in both military and civil aviation. This presentation explores the past unique uses of elastomers in military aviation and defines the future needs of next generation aerospace vehicles. From the common tires to the exotic firewall seals, EMI shielding materials, and engine seals, elastomers have filled a much needed role in aerospace materials.  The Air Force Materials Laboratory at Wright -Patterson AFB has been an integral part in the development and application of elastomeric materials.  Beginning with fluorocarbon materials in 1948, many developments have been made to meet the challenging environments of aerospace flight. Through the years, specialized seals, coatings, elastomeric parts and sealants have been developed by the aerospace industry.  Today elastomers play a critical role on all aerospace platforms, both military and commercial.  Space adds its own unique requirements and many specialty elastomeric materials have played and important role in meeting mission requirements. Tomorrow the need is even greater with broader operating conditions and stricter requirements needed for sustained flight.  Although some may consider elastomers as a mature technology and on "cruise control", further developments are needed to withstand expanded operating conditions and support future needs.
