AIRCRAFT REPAIR USING BORON EPOXY
Boron/Epoxy patches (doublers) have been successfully used on aircraft for many years. Boron/Epoxy doublers are thinner and lighter than riveted aluminum doublers, and can be installed more quickly and cheaply. This application has been in existence for over 30 years, with much of the development done by the Australian Air Force. Over the years, more than 6000 doublers have been put into service in both commercial and military applications. Primary military applications in the U.S. include the C-130 and C-141 transports.

In March, 1996, while Specialty Materials, Inc. was then part of Textron Corporation, Textron funded Boeing Technical Services to perform an extensive evaluation of bonded Boron/Epoxy doublers for commercial aircraft metallic structures. This resulted in an installation process specification for bonding boron/epoxy to metallic aircraft structures.
