During the 70's, the availability of unniderectional boron biber fabric at Dassault Aviation did allow reinforcement of metallic structures by direct ply lay up on the mental. To be able to apply these reinforcement on airplanes, it was necessary to define a resin system inducing low thermal stresses in the metal during its cure, and with acceptable mechanical properties after aging. Validation was done by simple tests on samples, by application of test repairs on the major fatigue test of the Mercure airplane. Reinforcements of the type are in service for almost 20 years on the Mercure airliner.
