To form a cutout reinforcement according to the invention for a sandwich construction, according to the invention two methods are combined to improve the strength characteristics of a braid core which preferably consists of foamed material. For this purpose, a braiding is combined with fibre bundles which are pulled through holes in the braid core. As a result, the cutout reinforcement according to the invention for a sandwich construction has particularly outstanding strength characteristics, while the component has only a low weight.
La présente invention concerne une combinaison de deux techniques permettant d'assurer un renforcement des découpes pour une structure sandwich, en vue d'obtenir une âme tressée, de préférence composée de mousse, qui présente de meilleures caractéristiques de résistance. L'invention consiste à combiner un tressage et des faisceaux de fibres tirés à travers des trous dans l'âme tressée. Le renforcement des découpes pour structure sandwich selon l'invention permet d'obtenir des caractéristiques de résistance particulièrement avantageuses, avec un faible poids de l'élément de construction.
