Abstract:
(EN) The structure according to the invention is a structure comprising a resin, reinforcing fibers, and voids, wherein the volume content ratio of resin is within a range of from 2.5 vol% to 85 vol%, the volume content of reinforcing fibers is within a range of from 0.5 vol% to 55 vol%, voids are contained within the structure in a proportion within a range of from 10 vol% to 99 vol%, the thickness St of the structure satisfies the conditional expression: St ≥Lf2⋅(1-cos (θf)) when the length of the reinforcing fibers is taken to be Lf and the orientation angle of the reinforcing fibers in the cross-sectional direction of the structure is taken to be θf, and the compressive strength of the in-plane direction during 50% compression of the structure measured by JIS K7220 is 3 MPa or higher.
(FR) La structure selon l'invention est une structure comprenant une résine, des fibres de renforcement, et des vides, le rapport de la teneur volumique en résine est situé dans une plage de 2,5 % en volume à 85 % en volume, la teneur volumique en fibres de renforcement est située dans une plage de 0,5 % en volume à 55 % en volume, les vides sont contenus dans la structure en une proportion située dans une plage de 10 % en volume à 99 % en volume, l'épaisseur St de la structure satisfait à l'expression conditionnelle : St ≥Lf2⋅(1-cos (θf)) lorsque la longueur des fibres de renforcement est considérée comme Lf et l'angle d'orientation des fibres de renforcement dans la direction transversale de la structure est considérée comme θf, et la résistance à la compression de la direction dans le plan pendant une compression de 50 % de la structure, mesurée par JIS K7220, est de 3 MPa ou plus.
