• Structure And Properties

When Kevlar is spun, the resulting fiber has a tensile strength of about 3,620 MPa, and a relative density of 1.44. The polymer owes its high strength to the many inter-chain bonds. These inter-molecular hydrogen bonds form between the carbonyl groups and NH centers. Additional strength is derived from aromatic stacking interactions between adjacent strands. These interactions have a greater influence on Kevlar than the van der Waals interactions and chain length that typically influence the properties of other synthetic polymers and fibers such as .

• Kevlar Grades

Kevlar K-29 – in industrial applications, such as cables, asbestos replacement, brake linings, and body/vehicle armor.

Kevlar K49 – high modulus used in cable and rope products.

Kevlar K100 – colored version of Kevlar

Kevlar K119 – higher-elongation, flexible and more fatigue resistant

Kevlar K129 – higher tenacity for ballistic applications

Kevlar AP – 15% higher tensile strength than K-29

Kevlar XP – lighter weight resin and KM2 plus fiber combination

Kevlar KM2 – enhanced ballistic resistance for armor applications

• Production

Kevlar is synthesized in solution from the monomers 1,4-phenylene-diamine (para-phenylenediamine) and terephthaloyl chloride in a condensation reaction yielding hydrochloric acid as a byproduct. The result has liquid-crystalline behavior, and mechanical drawing orients the polymer chains in the fiber's direction. Hexamethylphosphoramide (HMPA) was the solvent initially used for the polymerization, but for safety reasons, DuPont replaced it by a solution of N-methyl-pyrrolidone and calcium chloride. As this process had been patented by Akzo (see above) in the production of Twaron, a patent war ensued.
