Aramid Fiber

Aramid fibers have excellent heat resistance. Many studies have shown that when heated at 300 degrees Celsius, this material still retains a fairly high strength of about 50 – 60%. Due to its high crystallinity, when exposed to high temperatures, aramid fibers shrink insignificantly. Aramid fibers have a breaking strength 5 times higher than steel, with an index of up to about 3045 MPa. When strongly bent, aramid fibers show excellent flexibility, without significant damage after a strong impact with a tensile force of about 0.3%. At high temperatures, this type of fiber still shows excellent elasticity. This type of fiber can be easily combined with other materials. For example, aramid fibers can be combined with epoxy to create water resistance, or combined with rubber to increase flexibility.

What are the main applications of Aramid fibers?
Firefighting clothing: thanks to its excellent heat resistance, fabrics made from aramid fibers are widely used to design protective clothing for firefighters from clothes, helmets or heat-resistant shoes. A typical example is the MIL-G-181188B military clothing.

As a substitute for asbestos: as many warnings have emphasized, asbestos can cause a series of serious diseases when inhaled and is banned in many countries. Currently, aramid fibers can completely meet the requirements of replacing this material and are completely safe for human health. Typical products such as brake pads, roofing sheets, …

Production of protective clothing: due to its durability, excellent abrasion resistance and shaping, aramid fibers are used to produce protective armor for athletes, cyclists and are also used in the military.

Used as cables for engineering projects: a typical example is Hydro Quebec’s hydroelectric power station, which uses aramid fibers as conductors for erection. Thanks to its high elongation at break.

Production of sports equipment: typically sailcloth for boats, hull materials, skis, tennis strings, hockey sticks, etc.

Applications of aramid are very diverse, some other products that can be mentioned are tires, fire wicks, drum heads, fiber-optic cable systems, fiber-reinforced concrete, jet engine casings, thermoplastic pipes. reinforcement, hot air filter fabrics, etc.
