Abstract

Procédé d'avertissement d'un risque de rupture ou de déformation d'une pièce en matériau composite lorsqu'elle est soumise à un effort. Le procédé consiste à : - arranger lesdites fibres en une structure en treillis (3) obtenue par bobinage des fibres pour former des barres (31) se rejoignant ou se croisant en des nœuds (30), - concevoir au moins une partie (4) de la pièce (1) au travers d'au moins une barre dudit treillis et/ou d'au moins une barre supplémentaire créée à partir de nœuds supplémentaires et/ou d'un ou plusieurs nœuds dudit treillis, dont l'emplacement et la résistance à la rupture sont déterminés, - la partie (4) de la pièce (1) consiste en une portion identifiable extérieurement, et qui est conçue apte à subir une déformation lors de la rupture de ladite au moins une barre.Method for warning of a risk of rupture or deformation of a part made of composite material when subjected to a force. The process consists in: - arranging said fibers in a lattice structure (3) obtained by winding the fibers to form bars (31) joining or crossing in nodes (30), - designing at least a part (4) of the part (1) through at least one bar of said lattice and / or at least one additional bar created from additional nodes and / or one or more nodes of said lattice, whose location and breaking strength are determined, - part (4) of part (1) consists of an externally identifiable portion, and which is designed to be able to undergo deformation upon rupture of said at least one bar.
