• 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

• 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 Dyneema.

• Thermal Properties

Kevlar maintains its strength and resilience down to cryogenic temperatures (−196 °C); in fact, it is slightly stronger at low temperatures. At higher temperatures the tensile strength is immediately reduced by about 10–20%, and after some hours the strength progressively reduces further. For example: enduring 160 °C (320 °F) for 500 hours, reduces strength by about 10%; and enduring 260 °C (500 °F) for 70 hours, reduces strength by about 50%.
