(FR) PALE D'HÉLICE D'ÉOLIENNE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)A windmill blade which comprises reinforcing fibers in a toughened resin matrix. The resin matrix is made from a composition which comprises (a) one or more epoxy resins and/or one or more epoxy vinyl ester resins, (b) one or more reactive diluents, and (c) at least one amphiphilic block copolymer. The amphiphilic block copolymer comprises at least two different polyether blocks and is present in the composition in an amount of from about 0.5 % to about 10 % by volume, based on the total volume of the matrix composition.
(FR)L'invention concerne une pale d'éolienne qui comprend des fibres de renforcement dans une matrice de résine durcie. La matrice de résine est faite d'une composition qui comprend (a) une ou plusieurs résines époxy et/ou une ou plusieurs résines époxy ester vinylique, (b) un ou plusieurs diluants réactifs, et (c) au moins un copolymère à blocs amphiphile.
