Abstract A three dimensional composite panel structure is provided having a thickness less than about 22.5 cm, overall density less than 0.2 g/cm, and exhibiting a global modulus greater than 1.2 GPa and stiffness greater than 15 kN-m . The composite panel structure includes at least two fiber-reinforced mats interconnected in a spaced substantially parallel configuration by a skeletal web and a closed cell foam filling the spaces between the panels. The fiber-reinforced mats include a plurality of fibers in a low viscosity cured thermosetting resin matrix. L'invention concerne une structure de panneau composite tridimensionnelle présentant une épaisseur inférieure à environ 22,5 cm, une densité globale inférieure à 0,2 g/cm, et présentant un module global supérieur à 1,2 GPa et une rigidité supérieure à 15 kN-m . Cette structure de panneau composite comprend au moins deux mats fibreux interconnectés selon une configuration espacée, sensiblement parallèle, au moyen d'une âme d'ossature, et une mousse à alvéoles fermé remplissant les espaces compris entre les panneaux. Les mats fibreux comprennent une pluralité de fibres prises dans une matrice de résine thermodurcissable durcie, présentant une faible viscosité.
