A method includes wetting fibers with a resin capable of being cured by at least two different cure treatments. At least partially curing the resin by subjecting the resin to a first cure treatment (36) and at least partially curing the resin by subjecting the resin to a second cure treatment. A plurality of fibers are located adjacent each other so that a plurality of valleys (34) are formed between the plurality of fibers along an outer side of the reinforcement. The resin is cured to retain the valleys in the outer side of the reinforcement. The outer side of the reinforcement is adhered to the structural member (44). An apparatus including a fiber locating mechanism adapted to retain the peaks and valleys during curing of the resin without rigidly confining the outer side of the reinforcement.

Ce procédé consiste à imprégner des fibres d'une résine pouvant être durcie par au moins deux différents traitements de durcissement. Le procédé consiste à durcir au moins partiellement la résine en la soumettant à un premier traitement de durcissement, et à durcir au moins partiellement la résine en la soumettant à un second traitement de durcissement. Une pluralité de fibres sont disposées adjacentes les unes aux autres de telle sorte qu'une pluralité de creux sont formés entre la pluralité de fibres le long d'une face extérieure du renforcement. La résine est durcie afin de conserver les creux dans la face extérieure du renforcement. La face extérieure du renforcement est collée à l'élément structural. Un appareil comprend un mécanisme de disposition de fibres adaptés pour conserver les sommets et les creux pendant le durcissement de la résine sans confiner de façon rigide la face extérieure du renforcement.
