Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene ( UHMWPE , "Dyneema") laminated between two sheets of polyester .
M5 has a tensile strength of 4 GPa [1] to 9.5GPa. [2] Other aramids- (such as Kevlar and Twaron) or UHMWPE-fibres (such as Dyneema and Spectra) range from 2.2 to 3.9 GPa. [3]M5 has "very high levels" of fire resistance, flame retardancy, and chemical resistance, especially high for an organic fiber.
A typical Top used in rope making. A top is a hand tool with an iron loop and hook used in the creation and splicing of rope. A Top is used to simultaneously hold a piece of rope while providing a hole to separate the "lays" (or strands) of synthetic or natural rope for splicing. A variation of a Top, the gripfid, is used for ply-split braiding ...
Webbing is cut with a hot wire as is nylon rope, which prevents fraying and unravelling. However, when webbing does fray and unravel, the result is less disastrous than with rope, providing a modest advantage. Webbing suffers the drawback of less elasticity than perlon rope, and it may be more difficult to handle with gloves or mittens on. [4 ...
A cable grip is a device for propelling a vehicle by attaching to a wire rope (called a haul rope) running at a (relatively) constant speed. The vehicle may be suspended from the cable, as in the case of aerial lifts such as a gondola lift ( télécabine ), may be guided by rails , as in a cable traction railway , or may be self-guiding, as in ...
Berberine, a plant compound traditionally used in herbal medicine, is today commonly stocked on the shelves of health food stores and pharmacies as a supplement. Beyond weight loss, berberine also ...
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid. Manufactured using an industrial machine known as a strander ...
