3D weaving material and method of 3D weaving for sporting implements

Methods for fabricating a 3D woven material and exemplary 3D woven material for sporting implements are disclosed. The exemplary weaves can be incorporated into any sporting implements, such as, baseball bats, lacrosse sticks, hockey sticks, rackets, helmets, and other protective equipment. The example sporting implement can be constructed, partially or entirely, with a woven or braided three dimensional structure. The 3D woven material can be a multi-directional layup having tows oriented in three directions (X, Y and Z) and also at any angle created by the combination of two or three directions. A single woven preform can be formed that can have a near net shape of the formed product, with the fibers oriented in a way that will be optimal for the particular application.

METHOD OF FABRICATING BOTH A WOVEN FIBER PREFORM AND A COMPOSITE MATERIAL PART

A method of fabricating a woven fiber preform that is impregnated with a matrix-precursor resin, the resin, in the raw state, presenting a glass transition temperature Tg.sup.0, includes: impregnating yarns or strands with the resin; feeding a loom with the impregnated yarns or strands maintained at a temperature in the range Tg.sup.0 to Tg.sup.0+10 C.; and weaving the yarns or strands in the loom in order to obtain the resin-impregnated woven fiber preform.

WOVEN MULTI-LAYER FABRICS AND METHODS OF FABRICATING SAME
20200354862 · 2020-11-12 ·

A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.

Docking device made with 3D woven fabric
10813749 · 2020-10-27 ·

A docking device for a bioprosthesis is disclosed that can change shape and recover after a deforming stress is removed, that adjusts to surrounding conditions to accommodate different complex anatomic geometries, and that mitigates leakage around the bioprosthesis. The docking device can include a 3D woven fabric forming an internal surface, an outer surface, and a thickness therebetween. A filler can be coupled to the outer surface. A method for making a docking device is also provided. The method includes weaving a 3D woven fabric by interlacing a shape memory material, a low-melt thermoplastic polymer or resin having a melting point, and a high-tenacity biocompatible material; and pressing and heating the 3D woven fabric over a shape-setting mold at temperatures greater than the melting point of the low-melt thermoplastic polymer or resin.

Woven fiber structure presenting a satin weave on at least one of its outside faces

A woven fiber structure presenting over at least one of its outside faces a satin weave formed by interlinking a first set of yarns with a second set of yarns; wherein the first set of yarns is in the majority over the outside face, the first set of yarns being formed by a mixture of yarns having an S-twist and of yarns having a Z-twist.
