Process for manufacturing a fibrous preform for reinforcement of parts made of composite material with a high local variation in thickness

A manufacturing process of a fibrous preform for a composite material includes creating a fibrous texture by three-dimensional or multilayer weaving between a plurality of weft layers and warp layers, the fibrous texture including an extra-thick portion having a sacrificial portion and a useful portion adjacent to the sacrificial portion in the warp direction, the sacrificial portion, placing the fibrous texture in a forming toolset, shaping the fibrous texture so as to obtain a fibrous preform having a sacrificial portion and an adjacent useful portion, removing the sacrificial portion from the fibrous preform. When weaving the fibrous blank, one or more expansion elements are inserted into the weft layers located at the core of the sacrificial portion of the fibrous texture. Each expansion element has a cross-section greater than the cross-section or count of the weft threads or strands present in the useful portion.

SEDIMENT-CONTROL FENCES WITH ANISOTROPIC STRENGTH AND STIFFNESS PROPERTIES

Sediment-control fences designed to withstand hydrostatic forces associated with elevated backwater against the fence are disclosed. The fences are made of anisotropic fabric having different mechanical properties such as strength and stiffness in the machine direction versus the transverse direction. The anisotropic fabric may include fibrillated yarns in one direction and monofilaments in another direction. The sediment-control fences may be used without the necessity of wire or chain-link backed supports that are conventionally used to resist structural failure due to hydraulic overtopping of the fences.

Composite low-twist yarn towel and production method thereof
11732388 · 2023-08-22 · ·

A composite low-twist towel that is formed of three parts: terry yarn, ground warp yarn and weft yarn. The ground warp yarn and the weft yarn are normal towel yarns and the terry yarn is a composite low-twist yarn. The composite low-twist yarn is composed of two yarns of different thickness, among them, the spun yarn is synthetic fiber spun yarn or filament yarn, and the thick yarn is the pure cotton yarn or the blended yarn of pure cotton and other fibers. The composite low-twist yarn is made into a warp beam through warping and sizing. Then, it interweaves with ground warp yarns and weft yarns through a towel loom or warp loom to form terry fabrics.
