Stitched double layer composite hose and manufacturing method thereof

A stitched double layer composite hose is provided. The stitched double layer composite hose includes a middle fabric pipe layer, an inner surface composite colloid material layer and an outer surface composite colloid material layer. The structure of the fabric pipe layer is weft-stitched double-layer unit structure. The double-layer unit structure includes an outer layer, an inner layer and stitched wefts. The inner layer includes inner layer warps and inner layer wefts; the outer layer includes outer layer warps and outer layer wefts. The stitched wefts interweave with the outer layer warps and the inner layer warps for conjoining the inner layer and the outer layer together. The fabric pipe layer weaved solves problems of the stitched double layer composite hose in the fabric pipe layer of traditional casing, with such advantages as high flexibility, less weaving point, less loss of yarn strength and less degree of torsion.

11572644 · 2023-02-07 · ·

Systems and methods are provided for consolidating a preform of braided fiber. One embodiment is a method that includes acquiring a braided preform comprising fibers of unidirectional material that have been woven into a shape having a closed cross-section, disposing the braided preform within a mandrel, disposing an inflatable bladder within the closed cross-section of the braided preform, and iteratively applying pressure to the braided preform via the bladder to consolidate the braided preform against the mandrel.

Reinforcement layer

Described herein are embodiments of a pressure hose having an improved reinforcement layer. In some embodiments, the reinforcement layer of the pressure hose has a reinforcement volumetric ratio (RVR) of greater than or equal to 110%. The reinforcement layer can include a plurality of braided beams, with each beam comprising a plurality of ends. In some embodiments, the plurality of ends within a beam are arranged in a multi-layer orientation. In some embodiments, the number of ends and the end orientation within each beam is identical amongst all beams in the reinforcement layer. The shape, size, and arrangement of the ends within a beam can all be adjusted to increase the surface area to volume ratio and, correspondingly, the RVR of the reinforcement layer.
