Abstract | Provided is a molded fiber-reinforced composite material that can have increased strength with respect to force from a direction perpendicular to the axial direction thereof, and that is such that deformation of a honeycomb core member in a direction perpendicular to the axial direction thereof is suppressed. The present invention is configured from: a reinforcing substrate (31) resulting from overlapping a plurality of prepreg sheets (31a) resulting from impregnating carbon fibers with an epoxy resin; a roof main body (2) that is superposed on the reinforcing substrate (31) and that results from overlapping a plurality of prepreg sheets (2a) resulting from impregnating carbon fibers with an epoxy resin; a joined section (4) formed from heating and compressing the reinforcing substrate (31) and the roof main body (2); a closed space (5) formed between the reinforcing substrate (31) and the roof main body (2) and encircled by the joined section (4); and a honeycomb core member (32) that is contained within the closed space (5) and that is such that outer peripheral cells (32a) are filled with an epoxy resin (J).
L'invention concerne un matériau composite moulé renforcé de fibres, qui peut présenter une résistance accrue à une force qui lui est appliquée depuis une direction perpendiculaire à sa direction axiale, et peut présenter une constitution telle que la déformation d'un élément central en nid d'abeilles dans la direction perpendiculaire à sa direction axiale est supprimée. Le matériau de l'invention est conçu à partir: d'un substrat de renforcement (31) obtenu par superposition d'une pluralité de feuilles pré-imprégnées (31a) résultant de l'imprégnation de fibres de carbone avec une résine époxyde; d'un corps principal de couverture (2) superposé au substrat de renforcement (31) et obtenu par superposition d'une pluralité de feuilles pré-imprégnées (2a) résultant de l'imprégnation de fibres de carbone avec une résine époxyde; d'une section jointive (4) formée par chauffage et compression du substrat de renforcement (31) et du corps principal de couverture (2); d'un espace fermé (5) formé entre le substrat de renforcement (31) et le corps principal de couverture (2), et entouré de la section jointive (4); et d'un élément central (32) en nid d'abeilles confiné à l'intérieur de l'espace fermé (5) et présentant une constitution telle que des cellules périphériques extérieures (32a) sont remplies d'une résine époxyde (J). |
