Zusammenfassung:	A structural reinforcement member is provided to be affixable to a metallic member. The metallic member defines a stress concentration section at which the metallic member is subject to loading in at least one direction such that stress is generated at the stress concentration section in at least one corresponding principal stress direction. The structural reinforcement member includes a polymer matrix composite (PMC) patch element and a bondline. The PMC patch element includes fibers suspended within a polymer matrix. The bondline is disposed to affix the PMC patch element to a surface of the metallic member at the stress concentration section such that the fibers extend along the principal stress direction. Selon l'invention, un élément de renforcement structurel est prévu pour pouvoir être fixé à un élément métallique. L'élément métallique définit une section de concentration des contraintes au niveau de laquelle l'élément métallique est soumis à une charge dans au moins une direction de telle sorte que la contrainte soit générée au niveau de la section de concentration des contraintes dans au moins une direction de contrainte principale correspondante. L'élément de renforcement structurel comprend un élément de plage en composite à matrice polymère (PMC) et une ligne de liaison. L'élément de plage PMC comprend des fibres en suspension à l'intérieur d'une matrice polymère. La ligne de liaison est disposée de manière à fixer l'élément de plage PMC à une surface de l'élément métallique au niveau de la section de concentration des contraintes de telle sorte que les fibres s'étendent le long de la direction de contrainte principale.
