Trim piece with variable stretch characteristics
11255029 · 2022-02-22 · ·

Elastic trims and articles incorporating the same, and also methods of manufacturing and processing elastic trims and articles incorporating the same, are provided. An elastic trim may include a base textile that is knitted or woven, and may further include cables that are movably positioned in tunnel structures located within the base textile, the cables having a lower stretch characteristic than the base textile. The cables may be secured and removed at certain locations, thereby imparting a variable stretch characteristic to the elastic trim. The elastic trims may be incorporated into various articles, including waistbands, apparel, footwear, and bags.

Hybrid chain link

The present invention relates to a chain link comprising a strip comprising warp yarns and weft yarns, with the warp yarns containing warp yarn A and warp yarn B, with the minimum creep rate of warp yarn B being higher than the minimum creep rate of warp yarn A, wherein the strip comprises a longitudinal core section and at least two longitudinal edge sections, and wherein the concentration of warp yarn A in the core section is higher than the concentration of yarn A in the edge sections of the strip and the concentration of warp yarn B in the edge sections is higher than the concentration of warp yarn B in the core section of the strip. The invention also relates to a chain comprising said chain link and to use of said chain in different applications.

Exotensioned structural members with energy-absorbing effects
09739061 · 2017-08-22 ·

Structural members having enhanced load bearing capacity per unit mass include a skeleton structure formed from strips of material. Notches may be placed on the strips and a weave of tensile material placed in the notches and woven around the skeleton structure. At least one pair of structural members can be jointed together to provide very strong joints due to a weave patterns of tensile material, such as Kevlar, that distributes stress throughout the structure, preventing stress from concentrating in one area. Methods of manufacturing such structural members include molding material into skeletons of desired cross section using a matrix of molding segments. Total catastrophic failures in composite materials are substantially avoided and the strength to weight ratio of structures can be increased.

Fiber preform for a turbine engine blade made of composite material and having an integrated platform, and a method of making it

A method of making a fiber preform, and the preform, for fabricating a turbine engine blade out of composite material, the method including: making a single-piece fiber blank by three-dimensional weaving with layers of longitudinal yarns interlinked by yarns of layers of transverse yarns; and shaping the fiber blank to obtain a single-piece fiber preform including a portion forming an airfoil preform and at least one portion forming a platform preform. During weaving, yarns of a first group of longitudinal yarns are extracted from the fiber blank beside one of side faces of the blank to form a portion corresponding to a blade platform preform, and yarns of a second group of longitudinal yarns are inserted into the fiber blank with mutual crossing of the yarns of the first group and the yarns of the second group.
