The present embodiments provide a woven element having a first plurality of warp threads extending in a first direction and integrated into a first surface on a front side of the woven element. The woven element may have a second plurality of warp threads extending in the first direction, where the second plurality of warp threads is integrated into a second surface on a back side of the woven element. A first weft thread may extend in a second direction, where a first portion of the first weft thread is positioned in front of at least one warp thread of the first plurality of warp threads to form at least a portion of a graphic image on the front surface. A second portion of the first weft thread may extend between the first plurality of warp threads and the second plurality of warp threads.

A fibrous preform for forming the fibrous reinforcement of a composite material part, the fibrous preform being made as a single piece and obtained by three-dimensional weaving, the preform including first and second skins and a longitudinal stiffening portion connecting the first to the second skin, the longitudinal stiffening portion forming a stiffening element of the part in the longitudinal direction. The preform has an intermediate portion extending in the longitudinal direction between two end portions. The longitudinal stiffening portion includes, in the intermediate portion, longitudinal non-woven threads or strands held together by first transverse threads or strands coming from the first skin and second transverse threads or strands coming from the second skin. In the end portions, the longitudinal threads or strands of the longitudinal stiffening portion are woven with the transverse threads or strands.

The present invention is directed to a three-dimensional composite fabric including a three-dimensional woven fabric, and a nonwoven fabric arranged on a first, on a second side, or on both sides of the three-dimensional woven fabric, wherein the composite fabric retains at least 15% thickness at a compression of about 200 pounds per square foot (psf) to about 1000 pounds per square foot. Further, the present invention is directed to a method of making a three-dimensional composite fabric and a method of installing the three-dimensional composite fabric in a landfill.

A method of manufacturing a preform including a core and a sole includes contour weaving the preform on a lap roller having a groove or an outgrowth allowing shape weaving of the core and the sole of the preform. At least one portion of the core and at least one portion of the sole include weft yarns which cross each other on common warp yarns.

Methods for fabricating a 3D braided material and exemplary 3D braided material for sporting implements are disclosed. The exemplary braids 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 braided three dimensional structure. The 3D braided 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.

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.

An rear fairing for a pylon supporting an aircraft turbojet engine forms an aerodynamic surface covering the base of the pylon. The rear fairing is elongated in a longitudinal direction and includes a floor arranged opposite the hot gases exiting the turbojet engine and side walls constituting aerodynamic surfaces. The floor and the side walls include ceramic matrix composite materials made from preforms formed by layers of superimposed warp and weft yarns, the preforms have interlayer weaving yarns connecting the layers to one another.
