Dyneema composite fabric (DCF) is a laminated material consisting of a grid of Dyneema threads sandwiched between two thin transparent polyester membranes. This material is very strong for its weight, and was originally developed for use in racing yacht sails under the name 'Cuben Fiber'.
DuPont made public in 1938 that their company had invented nylon. [1] This new invention was the first synthetic fiber, fabrics that are commonly used in textiles today. [2] In 1939, DuPont began marketing nylon monofilament fishing lines; however, braided Dacron lines remained the most used and popular fishing line for the next two decades, as early monofilament line was very stiff or "wiry ...
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 .
Webbing is less likely to loosen itself off the rock than tubular rope. Note that webbing construction is either utterly flat or flat-tubular; the latter tends to handle better but knots are more likely to jam. The most popular knots in webbing are the water knot and the grapevine knot. The latter is stronger, but uses more webbing for the knot.
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Braided lines often have 1/3 to 1/4 the diameter of mono or fluorocarbon lines at a given test breaking strength. Therefore, it is easy to fit much longer braided line on a spool than monofilament or fluorocarbon line for the same strength. This is very important for deep sea fishing, since reels don't have to be very big to accommodate long lines.
Dyneema/Spectra slings are usually sewn not tied due to very high lubricity which leads to poor knot-holding ability and has led to the recommendation to use the triple fisherman's knot rather than the traditional double fisherman [3] Sewn slings have a rated breaking strength of at least 22 kilonewtons (4,900 lb f).
The specific strength is bounded to be no greater than c 2 ≈ 9 × 10 13 kN⋅m/kg, where c is the speed of light. This limit is achieved by electric and magnetic field lines, QCD flux tubes, and the fundamental strings hypothesized by string theory. [citation needed]
