Unbraided corrugated tube elongates when pressurised above a certain level. To restrain this, a minimum of one external layer of braid is recommended, preventing longitudal expansion of the corrugated tube and thus increasing the internal pressure strength of the tube. Our braids are also commonly used to sheeth hydraulic hoses, rubber hoses, plastic hoses and a wide range of other applications. Available in a variety of standard coil lengths and special lengths available upon request. Braid is highly flexible and follows the movement of the hose. Excellent chemical resistance, durability and corrosion resistance.

A rope is a bundle of flexible fibers twisted or braided together to increase its overall length and tensile strength. The use of ropes for hunting, carrying, lifting, and climbing dates back to prehistoric times. Ropes were originally made by hand using natural fibers.
Modern ropes are made by machines and utilize many newer synthetic materials to give them improved strength, lighter weight, and better resistance to rotting. More than half of the rope manufactured today is used in the fishing and maritime industries. Although the origin of rope is unknown, the Egyptians were the first people to develop special tools to make rope. Egyptian rope dates back to to B.
Other Egyptian rope was made from the fibers of date palms, flax, grass, papyrus, leather, or camel hair. The use of such ropes pulled by thousands of slaves allowed the Egyptians to move the heavy stones required to build the pyramids.
By about B. Rope and the craft of rope making spread throughout Asia, India, and Europe over the next several thousand years. By the fourth century, rope making in India had become so specialized that some makers produced rope intended only for use with elephants.
Leonardo da Vinci drew sketches of a concept for a ropemaking machine, and by the late s several working machines had been built and patented. Rope continued to be made from natural fibers until the s when synthetic materials such as nylon became popular. Despite the changes in materials and technology, rope making today remains little changed since the time of the ancient Egyptians.
Rope is sometimes generally referred to as cordage and can be divided into four categories based on its diameter. Cordage under 0. These are not considered to be true rope. Cordage with a diameter of 0. Cordage over about 1. Rope construction involves twisting fibers together to form yarn. For twisted rope, the yarn is then twisted into strands, and the strands twisted into rope. Three-strand twisted rope is the most common construction.
For braided rope, the yarn is braided rather than being twisted into strands. Double-braided rope has a braided core with a braided cover. Plaited rope is made by braiding twisted strands. Other rope construction includes combinations of these three techniques such as a three-strand twisted core with a braided cover. The concept of forming fibers or filaments into yarn and yarn into strands or braids is fundamental to the rope-making process. Rope may be made either from natural fibers, which have been processed to allow them to be easily formed into yarn, or from synthetic materials, which have been spun into fibers or extruded into long filaments.
Natural fibers include hemp, sisal, cotton, flax, and jute. Another natural material is called manila hemp, but it is actually the fibers from a banana plant. Sisal was used extensively to make twine, but synthetic materials are replacing it. Manila rope is still used by traditionalists, but it can rot from the inside, thus losing its strength without giving any outward indication. Synthetic fibers include nylon, polyester, polypropylene and aramid.
Polypropylene costs the least, floats on water, and does not stretch appreciably. For these reasons it makes a good water ski tow rope. Nylon is moderately expensive, fairly strong, and has quite a bit of stretch. It makes a good mooring and docking line for boats because of its ability to give slightly, yet hold. Aramid is the strongest, but is also very expensive.
Nylon and polyester may be spun into fibers about inches cm long. Ropes made from spun synthetic fibers feel fuzzy and are not as strong as ropes made from long, continuous filaments. Some ropes use two different synthetic materials to achieve a combination of high strength and low cost or high strength and smooth surface finish. Wire rope may be made from iron or steel wires. This is commonly referred to as cable and is used in bridges, elevators, and cranes.
It is made by a different process than fiber or filament ropes. Fibers and filaments are first formed into yarn. The yarn is then twisted, braided, or plaited according to the type of rope being made. The diameter of the rope is determined by the diameter of the yarn, the number of yarns per strand, and the number of strands or braids in the finished rope. If the rope is to be made from long filaments of synthetic material, several filaments are grouped together in a process called doubling or throwing.
This produces a sliver of multiple plies of filaments. The level of quality control depends on the intended use of the rope. Ropes intended for general purpose use are sold by diameter and tensile strength. Tensile strength is determined by breaking a sample piece under load. Basic raw material specification and a visual inspection are the only quality control measures used for these ropes.
Ropes intended for high-risk applications—such as rappelling, rescue work, and lifting objects over people—are more closely inspected and tested. These ropes have a finite service life and may also have a color code or other coding to indicate the date of manufacture. Some ropes incorporate some type of wear tracer formed into the rope. These tracers are usually a single yarn of contrasting color placed just under the outer wrap of yarn.
Should any abrasion or overextension of the rope occur, this filament would be exposed, indicating an unsafe condition and requiring that the rope be replaced.
The future of rope making is directly linked to improvements in materials. Over the years, almost every conceivable type of rope configuration has been attempted. In the past, new materials have allowed rope makers to reduce the diameter of the rope while maintaining the tensile strength and improving the resistance to weathering and abrasion. It is expected that a new generation of very strong, very light fibers and forming techniques will produce even further improvements in ropes.

Affordability The primary drive for low cost lightweight composite structures has resulted in a number of new technologies with potential for automation. For thermoset materials, low cost fabrication can be achieved with automated preform fabrication, such as braiding and automated tow placement, followed by one of various resin injection techniques. Low cost fabrication of thermoplastic components can be achieved by press forming and by fibre placement with in-situ consolidation. Other processes may require the use of an autoclave.
Braid is most commonly manufactured and used as a freestanding fabric with a constant braid angle the acute angle measured from the axis of the braid to the axis of the bias yarns for a given diameter. Braided-fiber architecture resembles a hybrid of filament-wound and woven material. Like filament winding, tubular braid features seamless fiber continuity from end to end of a part. Like woven materials, braided fibers are mechanically interlocked with one another, but because the fibers are also continuous, braid has a natural mechanism that evenly distributes load throughout the structure. This efficient distribution of load also makes braided structures very impact resistant. Since all the fibers in the structure are involved in a loading event, braid absorbs a great deal of energy as it fails. This is why braid is used as fan blade containment in commercial aircraft and for energy-absorbing crash structures in Formula One racing cars. Braided fibers are coiled into a helix just like wire in a spring. The difference, however, is the mechanical interlocking. As a structure is exposed to high fatigue cycles, cracks will propagate through the matrix of filament-wound or unidirectional prepreg laid-up structures.
