The invention relates to a method (30) for producing a molded body (52) from a fiber material (50), wherein a textile structure (54) that is provided with a binder material is first produced from the fiber material (50) using a textile technology (step 32). This textile structure (54) is subsequently shaped (step 34) and fixed in a predetermined three-dimensional form by an activation of the binder material (step 36). The activation of the binder material (step 36) is carried out iteratively here. This means that the binder material is activated progressively in some selected areas of the textile structure (54) (and the shape of the structure is fixed in these areas as a result) before an activation/fixing is carried out in other areas of the textile structure (54).

A method of fabricating a fiber structure by multilayer three-dimensional weaving between a plurality of weft yarns and of warp yarns, the fiber structure having at least first and second portions that are adjacent in the warp direction, the first portion presenting, in a direction perpendicular to the warp and weft directions, a thickness greater than the thickness of the second portion, includes making the first portion using a step of three-dimensionally weaving warp and weft layers in which a fiber fabric is formed in the form of a Mock-Leno weave grid in a core of the first portion together with skins at a surface of the first portion, a weave of the skins being modified locally so as to deflect certain warp yarns from said skins and weave them with the fiber fabric in the form of the Mock-Leno weave grid.

A fibrous texture in the form of a web includes a first portion extending in a longitudinal direction between a proximal part and an intermediate part. One or more layers of warp threads or strands present on the side of an inner face of the fibrous texture include threads or strands of glass fibers, the threads or strands of the other layers of warp threads or strands including threads or strands of carbon fibers. The fibrous texture further includes a second portion extending in the longitudinal direction between the intermediate part and a distal part of the fibrous texture. One or more of the plurality of layers of warp threads or strands present on the side of an outer face of the fibrous texture include threads or strands of glass fibers. The warp threads or strands are continuous over the entire length of the fibrous texture.

A method for weaving a three-dimensional preform includes the following steps: decomposing and determining performance requirements of different functional locations of the parts; selecting guide sleeves and fibers of each of the functional locations and designing a parameter; selecting guide sleeves and fibers of a transition area and designing a parameter, thereby implementing smooth transition of the transition area; determining a weaving sequence according to layouts of the guide sleeves and winding manners of the fibers in the functional locations and the transition area to generate a fiber iterative instruction for layer-by-layer weaving; arranging guide sleeves according to design requirements of the functional locations and the transition area to generate a guide sleeve array; and driving a weaving mechanism to select different fibers for subarea weaving layer by layer to obtain the three-dimensional preform having a gradient structure.

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.

A multi-ply woven gauze that has loft, a soft texture, and superior heat retention, permeation resistance, and lightness of weight. The multi-ply woven gauze includes a front surface layer formed with a plain-weave structure, an intermediate layer formed with a waffle-weave structure, and a rear surface layer formed with a plain-weave structure. The front surface layer and the intermediate layer are joined together, and the rear surface layer and the intermediate layer are joined together. Wrinkles form at the connections between the front surface layer and the rear surface layer due to the difference in contraction between the plain-weave structures and the waffle-weave structure. The intermediate layer is formed from at least one layer. The weave density of a single layer in the intermediate layer is equal to or half the weave density of the front surface layer and the rear layer.

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.

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.

A fibrous preform obtained by three-dimensional weaving, comprising a first skin, a second skin, and a central portion connecting them and forming a stiffening element. In a transverse plane, transverse threads of the first skin and the second skin are woven in pairs in the first skin and the second skin on either side of the central portion; the threads of a first pair of the first skin and of a second pair of the second skin are separated into two unitary threads at the central portion by being woven with longitudinal threads, and a thread of the first pair crosses a thread of the second pair at least twice in the central portion.
