A method of fabricating a docking device involves implementing a three-dimensional (3D) weaving technique to form a 3D textile structure using a plurality of different types of fibers, heating the 3D textile structure on a shape-setting mold at a temperature above a melting point of a first type of fiber of the plurality of different types of fibers to set a cylindrical shape of the 3D textile structure, maintaining the 3D textile structure on the shape-setting mold to cool off for a period of time, and removing the 3D textile structure from the shape-setting mold.

A reinforcing fiber structure for a propeller blade made of composite material is woven as a single piece to have an airfoil, a spar portion, and an enlarged portion. The fiber structure includes a zone of non-interlinking extending between the front and rear edges of the airfoil, and extending between an intermediate zone and the bottom edge of said airfoil. The spar portion extends inside the airfoil in the zone of non-interlinking, the spar portion extending outside the airfoil through the bottom edge of said airfoil. The enlarged portion extends from the spar portion outside the airfoil. The airfoil includes skins that are not interlinked with each other in the zone of non-interlinking and that surround the spar portion. The skins define two housings present inside the airfoil on respective sides of the spar portion and opening out through the bottom edge of the airfoil.

A partially degradable polymeric fiber includes a thermally degradable polymeric core and a coating surrounding at least a portion of the core. The thermally degradable polymeric core includes a polymeric matrix including a poly(hydroxy-alkanoate), and a metal selected from the group consisting of an alkali earth metal and a transition metal, in the core polymeric matrix. The concentration of the metal in the polymeric matrix is at least 0.1 wt %. The partially degradable polymeric fiber may be used to form a microvascular system containing one or more microfluidic channels.

A woven fabric includes first and second woven fabric layers with an intermediate layer in between, which form a sensor with an electrical characteristic that changes while a force is acting on the woven fabric. The first layer includes electrically conductive strips and electrically non-conductive strips arranged adjacent to one another in an alternating manner. The second layer includes alternating conductive strips and non-conductive strips that extend transverse to the strips of the first layer. At least some of the threads in each of the conductive strips of the first layer are conductive weft threads. At least some of the threads in each of the conductive strips of the second layer are conductive weft threads. The non-conductive strips of the first and second layers are weft threads.

The invention concerns a method for manufacturing a turbomachine flow straightener made from composite material having a blade extended by at least one attachment end, comprising the operations of: forming a fibrous blank from a three-dimensional fabric comprising warp threads oriented in a direction corresponding to the longitudinal direction of the blade to be manufactured; dividing at least one end of the fibrous blank by separating in order to constitute at least two sets of integrated layers; shifting at least one set of integrated layers in a planar configuration such that the warp threads are inclined in this set of integrated layers relative to the orientation of the warp threads in the fibrous blank portion of the blade.

This document describes techniques and apparatuses for connecting an electronic component to an interactive textile. Loose conductive threads of the interactive textile are collected and organized into a ribbon with a pitch that matches a corresponding pitch of connection points of the electronic component. Next, non-conductive material of the conductive threads of the ribbon are stripped to expose the conductive wires of the conductive threads. After stripping the non-conductive material from the conductive threads of the ribbon, the connection points of the electronic component are bonded to the conductive wires of the ribbon. The conductive threads proximate the ribbon are then sealed using a UV-curable or heat-curable epoxy, and the electronic component and the ribbon are encapsulated to the interactive textile with a water-resistant material, such as plastic or polymer.

A strip-shaped fibrous texture has a three-dimensional or multi-layered weaving between a plurality of layers of warp yarns or strands and a plurality of layers of weft yarns or strands extending in the lateral direction. The fibrous texture includes a first section extending along the longitudinal direction from a proximal portion of the texture and in which one or more layers of the plurality of layers of weft yarns or strands consist of a plurality of groups of yarns or strands each including at least one carbon fiber yarn or strand and one glass fiber yarn or strand. The carbon fiber yarn or strand and the glass fiber yarn or strand of each group of yarns being woven together according to the same weaving pattern or weave. The fibrous texture further includes a second section present between the first section and a distal portion of the fibrous texture.

Provided is 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 comprises 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.

A blade is provided including a structure made of composite material including a fibrous reinforcement obtained by three-dimensional weaving and a matrix in which the fibrous reinforcement is embedded, the structure made of composite material including an aerodynamically profiled blade portion and a blade root portion, the blade root portion including two sections each connected to the blade portion, a blade root fastening part including a wall delimiting a cavity and an opening formed in the wall, the structure made of composite material extending through the opening so that the blade portion is located outside the fastening part and the blade root portion is located inside the cavity, and a blocking part disposed in the cavity, between the two sections of the blade root portion, in order to keep the two sections apart from each other so as to oppose withdrawal of the blade root portion from the cavity via the opening.
