Weaving assembly and method of using
Disclosed is a weaving assembly including a rotatable base, a base positional controller, a weave control grid, a warp fiber support, warp fiber arms, a warp fiber arm positional controller and a fill fiber wand.
WOVEN FABRICS FOR COMPOSITE COMPONENTS
A manufacturing method includes: in a loom, weaving a woven reinforcing fibre fabric including a plurality of reinforcing fibre tows and polymeric material; and heating the woven reinforcing fibre fabric as it exits the loom to cause the polymeric material to melt and/or cure.
FIBER STRUCTURE AND FIBER-REINFORCED COMPOSITE MATERIAL
A fiber structure includes a plurality of fiber layers stacked in a stacking direction and a plurality of binding yarns that bind the fiber layers together in the stacking direction. Each of the binding yarns is engaged with the first fiber bundles that configure two fiber layers located at opposite ends of the fiber structure in the stacking direction. Each first fiber bundle has an engagement portion as a section that is engaged with the binding yarn and a non-engagement portion as a section that is not engaged with the binding yarns. Regarding the engagement portion and the non-engagement portion, the dimension of the non-engagement portion in the stacking direction is greater than the dimension of the engagement portion in the stacking direction.
Moisture control fabrics
The present disclosure provides articles of manufacture with improved moisture control as well as methods of making such articles. In some embodiments, provided herein the article has a fabric with an outer hydrophobic surface and an inner surface with hydrophobic and hydrophilic regions where the hydrophilic regions can form a pattern, allowing moisture to collect and move through the pattern, and the hydrophobic regions prevent the whole inner surface from becoming moist and the outer hydrophobic regions does not show moisture. The fabric may be used to make garments. The entire inner surface of the garment may be patterned with hydrophilic patterns for partial absorption, and the entire outer surface of the garment is hydrophobic, thereby preventing perspiration from being seen from outside of the garment. Further provided herein are methods of making fabrics with improved moisture control including by printing or knitting.

METHOD FOR PREPARING CAPACITIVE STRESS SENSING INTELLIGENT FABRIC
A method for preparing a capacitive stress sensing intelligent fabric. Conductive yarn serves as an electrode of a capacitive sensor, and the conductive yarn is obtained by means of direct preparation, coating, doping, etc.; an insulating elastomer is coated on the conductive yarn as a dielectric material; and the conductive yarn, which has been subjected to insulation processing, is interlaced among common yarns by using interweaving and overlapping structures among fabric yarns. A fabric sensing array is formed by means of a common manufacturing technique, and the method can be widely applied to force monitoring, etc., for intelligent garments, intelligent homes, touch-control screens, electronic skin and three-dimensional fabric composite materials.
Method for producing a curved honeycomb structure made from composite material
A method of fabricating a curved cellular structure includes making an expandable fiber structure by multilayer weaving between layers of warp yarns and layers of weft yarns, the structure having zones of non-interlinking extending in the thickness of the structure, the non-interlinking zones spaced apart from one another by portions of interlinking between layers of weft yarns, the portions of interlinking offset by one or more weft yarns in a direction parallel to the direction of the layers of weft yarns between each series of these planes; impregnating the fiber structure with a resin; expanding the fiber structure on support tooling to form a cell in the fiber structure at each zone of non-interlinking, the tooling also presenting a curved shape corresponding to the shape of the cellular structure that is to be fabricated; and polymerizing the resin of the fiber structure to form a curved cellular structure.
Fiber composite material and preform and fan blade made therefrom
A fiber composite material comprises a polymer matrix, carbon fibers, and non-carbon fibers, wherein the non-carbon fibers have a strain to failure value greater than the strain to failure value of the carbon fibers. Also discussed is a preform comprising the fiber composite material combined in a three dimensionally woven structure. Also discussed is a fan blade for a jet engine.
SHIELDING DEVICE FOR SHADING AND RAIN PROTECTION PURPOSES
A shielding device for shielding against weather influences that includes a textile sheet material which is stretched two-dimensionally or can be rolled out and which forms a shield against weather influences, in particular, against solar radiation and/or rain. The textile material has warp threads and weft threads connected together in a lattice-like manner so as to form a fabric. A foam layer which has foam pores that are separated from one another by solid foam walls is applied onto the textile sheet material on at least one side of the textile sheet material.
SYSTEMS AND METHODS FOR CREATING TOPOGRAPHICAL WOVEN FABRIC
Provided are systems and methods for producing seamless woven materials that are variable in each of their 3 dimensions. The systems and methods generally operate by altering heddle positions independently to impart three dimensional structure to a woven fabric. Weft yarn is woven into a set of warp yarns that have been individually raised or lowered along a particular cross section, essentially locking the weave into an intended 3 dimensional form.
