The subject of the invention is a cable wrapping tape, in particular for wrapping cables in motor vehicles. The cable wrapping tape has a tape-like carrier and an adhesive coating on at least one side of the carrier. The carrier consists of a single woven layer. Moreover, the warp threads and weft threads of the carrier have different finenesses. The weft threads have a fineness of more than 200 dtex, while the weft threads have a fineness of 40 dtex to 100 dtex. According to the invention, the warp threads are formed with a high tensile strength and have a fineness-related highest tensile strength of more than 500 cN/dtex, in particular of more than 8 cN/dtex.

A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.

A belt for an elevator system and a method for making the same is provided. The belt includes a plurality of tension members that extend along a length of the belt and a jacket. The jacket substantially retains the plurality of tension members. The jacket maintains a desired spacing and alignment of the tension members relative to each other. The jacket includes a plurality of first fibers and a plurality of second fibers. The jacket defines at least one exterior, traction surface of the belt. The first fibers are at least partially disposed between the tension members and the traction surface of the belt. The second fibers are fill fibers. The first fibers have at least one property that distinguishes them from the second fibers.

Woven material and altering the weave pattern of the woven material. The woven material may comprise a first portion comprising a weave pattern formed by a plurality of warp threads and at least one weft thread woven between the plurality of warp threads. The first portion may have a first thickness. The woven material may also comprise a locally thinned portion positioned adjacent the first portion. The locally thinned portion may comprise an altered weave pattern, which may comprise the plurality of warp threads positioned on a single side of the at least one weft thread, and/or the at least one weft thread woven between the plurality of warp threads in the locally thinned portion is separated by a first distance. The first distance may be greater than a second distance positioned between the at least one weft thread woven between the plurality of warp threads in the first portion.

An innerduct for segregating cables in a conduit is provided wherein the innerduct is constructed from one or more strip-shaped lengths of a woven textile fabric and configured to provide multiple longitudinal compartments for the cables, and the textile fabric has a warp of monofilament yarn ends and a filling of a combination of monofilament and multifilament yarn picks, with the multifilament yarn picks being multiple-inserted yarns.

Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes several improved woven preforms that include circumferential or axial stiffeners, as well as methods of manufacturing the same. One embodiment includes circumferential stiffeners added to a woven preform. Another embodiment includes sub-preforms with integral flanges that combine to make integral stiffeners. A further embodiment includes an intermediate stiffener wrapped onto a base sub-preform wrap, wherein the intermediate stiffener wrap incorporates intermediate stiffeners. Another embodiment incorporates bifurcations in one or more layers of an outermost wrap of a multi-layer fabric composite that forms a preform, wherein the bifurcated outer wrap is folded to form stiffeners that may be oriented circumferentially or axially.

A method of preparing a woven fabric material for use in a ceramic matrix composite includes securing a woven fabric tape in tension across a roller, the roller having an outer surface with a plurality of spiked protrusions extending radially therefrom, each of the plurality of spiked protrusions having a diameter between 10 microns and 500 microns. The method further includes passing the woven fabric along the roller, such that the roller rotates with the passing of the woven fabric tape, thereby impinging the spiked protrusions into the woven fabric tape, and separating filaments within tows of the woven fabric tape by penetration of at least one of the spiked protrusions into the woven fabric tape, such that filaments within various tows of the woven fabric tape are pushed apart to form a separated woven fabric tape with a greater number of tows per unit area than the woven fabric tape.

An open box-like woven fabric includes two inner walls connected transversely between two outer walls, and a base wall connected to the outer and inner walls oppositely of a top opening formed between the outer and inner walls. Each outer wall has an outwardly extending side extension, and the base wall has an outwardly extending bottom extension. The open box-like woven fabric is formed from a novel flattened fabric preform.
