A machine and method are presented for producing interlaced composite components. The method includes: depositing a first one or more warp filaments onto a deposition surface in a first linear direction, inserting, on top of the first one or more warp filaments, a first one or more weft filaments in a second linear direction, where the second direction is in the same plane as the first one or more warp filaments but is not parallel to the direction of the first one or more warp filaments, depositing, on top of the one or more first weft filaments, one or more second warp filaments in first linear direction, where the second one or more warp filaments are not collinear with the first one of more warp filaments, and inserting, on top of the second one or more warp filaments, a second one or more weft filaments in the second direction.

An exemplary weaving method includes placing a first section of a fill fiber between warp fibers, forming a pick, moving a base to reposition the warp fibers, and placing a second section of the fill fiber between the warp fibers.

An apparatus for weaving a multilayer product that has one or more warp columns for placing warp fibers and one or more heddle columns for heddles for lacing the warp fibers. The weaving apparatus has a numerical ratio of warp columns and heddle columns that is a fractional number. And a portion of the warp fibers are laceable through heddles on one or more heddle columns based on the fractional number. A method for weaving a multilayer product where adjacent warp fibers are segmented and laced through heddles on the heddle columns based on the fractional number.

The present invention involves a Bi-axial bias weaving machine and two dimension woven structures (material) having interlaced bias strands. The material includes plain, twill and satin structures made of two bias flat strands (tape) interlacing each other at particular angles (30-60). The weaving machine includes bias holders assembly, chains, bias rapiers and take-up assembly. The embodiment of this invention may be utilized to produce high performance fabrics such as textile performs for aerospace composites.

The invention relates to a three-dimensionally woven multilayer fibrous structure (20) having the same number of warp yarns woven at any level along the warp direction, the fibrous structure (20) comprising, in the warp direction, a first part (22) and a second part (24), the first part (22) having a thickness measured in a direction perpendicular to the warp and weft directions, greater than the second part (24), characterised in that the spacing between two weft planes along the warp direction is greater in the second part than in the first part (22), and in that the number of weft yarns is lower in the second part (24) than in the first part (22).

A gas turbine fan casing made of composite material with a fibrous reinforcement includes a plurality of superimposed turns of a strip-shaped fibrous texture having a three-dimensional weaving between a plurality of layers of warp yarns and a plurality of layers of weft yarns, the fibrous reinforcement being densified by a matrix. The fibrous texture includes at least one lateral section of variable thickness in which the weft yarns have a size or a count different from the size or the count of the weft yarns of the plurality of layers of weft yarns present in the remainder of the fibrous texture.

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 machine and method are presented for continuously forming a woven composite with controllable internal fabric geometry. The machine may include one or more spools for dispensing one or more warp filaments, a roller assembly configured to receive a composite weave, a warp rack having warp heads for engaging the warp filaments and vertically adjusting position to dynamically create a weave pattern in response to the insertion of one or more weft filaments by a weft inserter stack.

A method of forming a substrate includes mapping a three dimensional spatial distribution of at least one structural protein fiber of extracellular matrix of biological material of interest, designing a fiber assembly pattern based on an intrinsic pattern of the at least one structural protein fiber of the extracellular matrix of the biological material, and assembling fibers based on the fiber assembly pattern to form the substrate.
