Abstract

Cette invention concerne un panneau structurel composite. Ce panneau comprend : un cadre comportant un axe de cadre longitudinal ; une pluralité d'éléments de poutre montés dans le cadre, chacun des éléments de poutre comportant un axe de poutre longitudinal sensiblement parallèle à l'axe du cadre ; un enveloppement de fibres de renforcement qui s'étend autour de chacun des éléments de poutre, lequel enveloppement présente un sens des fibres sensiblement oblique par rapport à l'axe des poutres ; une pluralité de torons métalliques qui s'étend autour de l'enveloppement, lesquels torons métalliques sont sensiblement parallèles à l'axe des poutres et à l'axe du cadre ; une couche extérieure d'un tapis de fibres de renforcement qui entoure le cadre, les poudres enveloppées et les torons métalliques, la plupart des fibres du tapis étant sensiblement parallèles à l'axe du cadre ; ainsi qu'une résine époxy solidifiée qui s'étend à travers et entoure les éléments de poutre, l'enveloppement des poutres, les torons métalliques, la couche extérieure et le cadre.
