What is Kevlar®? - DuPont

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.

Aramid Fiber

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.

Para-Aramid Fibre - an overview | ScienceDirect Topics

Para-aramid fibers possess outstanding resistance to cyclic loading conditions (Fig. 17.25).In particular, Kevlar and Technora have a fatigue resistance, which, some claim, is better than carbon fibers. (Yang, 1993).Bunsell (1975) reported that Kevlar 49 fibers fibrillated but did not fail unless the maximum applied load was greater than 80% of the tensile strength.

Aramid, Kevlar, Twaron,Nomex characteristics and properties

Para-aramid fibers such as Kevlar® and Twaron®, which are slightly different, have outstanding strength-to-weight properties, and have high tenacity which makes it difficult to cut or fray. High Rigidity Young's modulus (stiffness): 130-179 GPa compared to carbon Fiber 300 GPa and glass 81 GPa, low elongation to Break (does not stretch much).

The density of Kevlar ® 49 is 1.44 g/cm 3 or 0.052 lb/in 3. For comparison, carbon fiber has a density of 1.76 g/cm 3 or 0.064 lbs/in 3 respectively. Kevlar is less dense than carbon fiber and far less stiff. Tensile modulus is ~16msi vs. 33msi for standard modulus carbon. Additionally, Kevlar ® 49 sees 2.4% fiber

Finite Fiber Engineered Aramid Fibers

Aramid fiber has a highly crystalline polymer chain. Common tradenames include Twaron®, Technora® and Kevlar®. Finite Fiber aramid pulp is a dry processed engineered low fibrillation, short aramid fibril. Aramids have inherent high-heat and high-strength properties making it a practical choice in a variety of extreme application environments.

Aramid - Wikipedia

Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers.They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, and as an asbestos substitute.. The chain molecules in the fibers are highly oriented along the fiber axis.

Kevlar Scissors - Light Brigade

The Miller® KS-1 5.5″ Fiber Optic Kevlar® Scissors were made specifically for cutting Kevlar®, aramid, carbon, fiberglass, and other hard-to-cut reinforcement fabrics. The small teeth machined into the blade allow the scissors to "bite" into the fibers without letting them slip.

Aramid Fibers

The difference is in their structure, Kevlar® is a para-aramid while Nomex® is a meta-aramid. An aramid is a polyamide where at least 85% of the amide bonds are attached to aromatic rings. The first aramid produced was called Nomex® introduced by Du Pont in 1961. For this report we will dissect each fiber separately. Kevlar ®
