KEVLAR ® is a great choice for creating tough, impact-resistant parts. Keep in mind, it can be equally tough to work with when it comes to cutting, sanding, or machining. Fabricators usually select specialized scissors, like our Gingher ® Modified Kevlar Scissors (2733-A), for cutting KEVLAR fabric.Scissors used to cut KEVLAR should be set aside to cut KEVLAR only.
Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora.Developed at DuPont in 1965, this high strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material …
Kevlar ® aramid fiber is a high strength, intermediate modulus, organic fiber. Its high tenacity and low thermal shrinkage make it similar to S glass. It is inherently flame-resistant and self-extinguishing, charring at 800ºF (425ºC). Fabrics woven of Kevlar ® aramid fiber combine very high strength-to-weight properties with excellent ...
Created by Stephanie Kwolek, DuPont ™ Kevlar ® is a heat-resistant para-aramid synthetic fiber with a molecular structure of many inter-chain bonds that make Kevlar ® incredibly strong. Best known for its use in ballistic body armor, Kevlar ® also has many other applications because of its high tensile strength-to-weight ratio.

There are three grades of Kevlar available: Kevlar 29, Kevlar 49, and Kevlar 149. Tensile modulus is a function of molecular orientation. As a spun fiber, Kevlar 29 (a high toughness variant) has a modulus of 62 GPA (9 Mpsi). Heat treatment under tension increases crystalline orientation. The resulting fiber, Kevlar 49, has a modulus of 131 GPA.

Aramid Fiber(Kevlar) is the lightest and toughest fabric type widely used in the composites industry. Used today alone as a fabric for bullet-proof undershirts, impact and cut-resistant safety equipment, and as a flame retardant, Kevlar offers the highest advantages between use as fabric or as a composite material.
Kevlar Prepreg. Kevlar prepreg is manufactured by the infusion of para-aramid fiber fabrics with a controlled amount of epoxy resin. All our prepregs are protected with wax paper on one side and plastic film on the other. They come in rolls of 1m / 1.27m wide; Length is 50/100 meters. We have Kevlar prepregs in Plain and Twill weaves.
Carbon Fiber is by far the stiffer of the composite materials. The actual figures presented here are for comparison only. The important thing to take away is that Carbon Fiber is about twice as stiff as Kevlar, and about 5 times stiffer than glass. There are many types of Kevlar, glass, and carbon fiber and they all differ.
Kevlar is a fiber with incredible strength. Thanks to the way the fiber is manufactured using inter-chain bonds (imagine woven fibers at a microscopic level), alongside cross-linked hydrogen bonds that adhere to these chains (imagine small fibers that span across the surface of those woven fibers, creating a mesh), Kevlar has an impressive ...
Carbon fiber and Kevlar — is a heat-resistant and strong synthetic fiber. It is a distant relative of nylon or superpolyamide. Their main features: From a practical standpoint and aside from the obvious color difference, Kevlar is more abrasion- and impact-resistant than carbon fiber. Kevlar usually positioned internally in all areas of ...
Kevlar/Carbon Sheets. DragonPlate solid Carbon/Kevlar hybrid sheets are ideal for applications where a balance between stiffness and toughness must be achieved. Although Kevlar is not as stiff as carbon fiber, it offers higher puncture and fracture toughness. Because it is a tougher material, however, these panels may be slightly more difficult ...
