YSZ CERAMIC SUBSTRATE PROTECTED FIREPROOF HOSE
A hose is provided capable of meeting fireproof requirements per AS1055 under no flow condition. The hose has multiple layers including a yttria-stabilized zirconia (YSZ) flexible ceramic substrate layer disposed between first and second silicone rubber layers.
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.
Non-metallic flexible pipe and manufacturing method thereof
A nonmetallic flexible pipe and a manufacturing method thereof. The nonmetallic flexible pipe comprises, from the inside to the outside, an inner liner, a pressure bearing layer, an isolation layer, a tensile layer, a functional layer, and a protective layer, wherein two adjacent layers are non-rigidly bonded. The inner liner layer is made from a thermoplastic polymer. The pressure bearing layer is made from a fiber-reinforced resin-based composite material. The isolation layer is made from a thermoplastic polymer. The tensile layer is made from a resin-reinforced fiber material. At least one of an optical fiber, a cable, a tracing ribbon, a pipe for conveying a heat transfer medium, a pressure sensor, and a temperature sensor is provided in the functional layer. The protective layer is made from a thermoplastic polymer.
Layered tube and layer for use in same
A layer for directing a hydraulic fluid includes a first fluoropolymer, a first crosslinker, and an anti-static additive. The first fluoropolymer is present in an amount greater than 60 parts by weight, the first crosslinker is present in an amount of from about 1 to about 10 parts by weight, and the anti-static additive is present in an amount of from about 0.4 to about 4 parts by weight, each based on 100 parts by weight of the layer. The layer may be included in a layered tube. In addition to the layer, the layered tube also includes an outer layer. The outer layer includes a second fluoropolymer, which is the same as or different than the first fluoropolymer. The second fluoropolymer is present in an amount greater than 60 parts by weight based on 100 parts by weight of the outer layer.
WOVEN IRRIGATION TUBING, APPARATUS AND METHOD OF MAKING SAME
Woven irrigation tubing comprises a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

FIBER REINFORCED COMPOSITE MATERIALS, ARTICLES AND RELATED METHODS
A fiber-reinforced composite material having at least one reinforcement layer having one or more woven mats, unwoven mats, or bundle of fibers comprising a plurality of reinforcement fibers that has a binder-resin filling at least a portion of the voids of the reinforcement fibers. In some aspects, the binder-resin adheres to the reinforcement fibers and displaces the air voids at the interface between the reinforcement fibers and the binder-resin. The binder-resin has a relatively low viscosity less than at least about 20,000 centipoise at 176° C. and low molecular weight, which allows the reinforcement layer to maintain a low flex modulus while maintaining or increasing tensile modulus. The fiber-reinforced composite material can be utilized in various articles, such as a flexible fiber reinforced hose adapted for conveying fluids under pressure having at least one polymer layer that bonds to the binder-resin of the reinforcement layer, preferably being cross-linkable or cross-linked to the polymer layer.
