Kevlar is used extensively by both civilians and the military, the military use Kevlar as body armour because it does
not add much weight to hinder the movement of foot soldiers but can stop a 45 calliber bullet. 7.26 mm bullets from an AK47
can also be stopped by the Kevlar used on tanks and other military vehicles.
Kevlar can also be used as a replacement for steel in cables used for bridges and lifts. It is stronger, lighter and
more flexible so lift operating systems can be more compact and more efficient. However, steel is often the material of choice
in large scale situations like these because it is cheaper than Kevlar.

Kevlar also has many uses in fireproof products because of its high heat resistance. These include the breathing systems
used by firefighters and some oven gloves; however, most fireproof clothing is made from Nomex, a close relation to Kevlar.
Kevlar thread is used in fire resistant mattresses; its high strength and fire resistance means it will not break in a fire,
exposing the flammable inner material of the mattress.
The strength to weight ratio of Kevlar can also be out to good use in a variety of every day situations outside
of industry and the military, many products rely on being very strong and also lightweight. Common examples include:
- Body material on kayaks to provide extra protection from impact with rocks, without adding weight
- High-strength gloves to protect hands from cuts when handling excessively sharp or fast moving machinery
- Sports equipment such as hockey sticks and skis to increase durability and usability
- Tear proof sails on wind surfing and sailing equipment
- Shrapnel resistant shielding in jet engines to protect airline passengers from engine failure debris
- Lining in tyres to make them puncture proof without the need for a solid piece of heavy rubber
