CA 2279408

A network-like woven 3D fabric material (9) comprises select multilayer warp yarns (8) occurring substantially linearly, the remainder multilayer warp yarns (7) occurring in the helical configuration and two orthogonal sets of weft (12c and 12r) and such a network-like fabric construction (9) made possible through a dual-directional shedding operation of the weaving process. Such a fabric may additionally incorporate non-interlacing multi-directionally orientated yarns (n1-n8) across the fabric cross section to improve the fabric's mechanical performance. The produced 3D fabric material, which may be cut into any desired shape without the risk of splitting, may be used wholly or in parts in technical applications.

Une matière (9) de tissu tissé en 3D de type réseau comprend des fils (8) de chaîne multicouche sélectionnés disposés de manière sensiblement linéaire, les fils (7) de chaîne multicouche restant ayant une configuration hélicoïdale, ainsi que deux ensembles orthogonaux de trame (12c et 12r), cette construction (9) de tissu de type réseau étant rendue possible par une opération de formation de foule bidirectionnelle dans le processus de tissage. Ce tissu peut également comprendre des fils (n1-n8) non entrelacés et orientés de façon multi-directionnelle dans la section transversale du tissu afin d'en améliorer les performances mécaniques. La matière de tissu en 3D produite, laquelle peut être découpée dans n'importe quelle forme voulue sans risque de se défaire, peut être utilisée entièrement ou en parties dans des applications techniques.
