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'.
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.
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 .
Zylon body armor panels sometimes cost twice as much as Kevlar or 35% more than other advanced materials. [9] Despite "sticker shock", the marketing for Zylon body armor described incredibly low weight and thickness, but shockingly high protection, causing some to refer to it as a "miracle fiber".
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).
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 ...
Boron nanotubes are also stiffer than graphene, with a higher 2D Young's modulus than any other known carbon and noncarbon nanostructures. [6] Since borophene is theoretically predicted to have metallic electronic structures and boron is lighter than most elements, borophene is expected to be the lightest experimentally realizable 2D metal.

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]
