Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body armour, because of its high tensile strength-to-weight ratio; by this measure it is 5 times stronger than steel. It is also used to make modern drumheads that withstand high impact. When used as a woven material, it is suitable for mooring lines and other underwater applications.
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.
Meta-paramid / Nomex
Meta-paramid like Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is the premier example of a meta variant of the aramids (Kevlar is a para aramid). Unlike Kevlar, Nomex cannot align during filament formation and has poorer strength. However, it has excellent thermal, chemical, and radiation resistance for a polymer material(Such as Heat Resistant Conveyor Belt). Both the firefighting and vehicle racing industries use Nomex to create clothing and equipment that can withstand intense heat. Nomex has also been used for its acoustic qualities, a ceiling canopy of Nomex reflects high and mid frequency sound, providing reverberation, while letting lower frequency sound partially pass through the canopy.
Zylon / PBO
Zylon, which also called as PBO has 5.8 GPa of tensile strength, which is 1.6 times that of Kevlar. Like Kevlar, Zylon is used in a number of applications that require very high strength with excellent thermal stability up to 600℃.
The various applications of zylon including body armour, space elevator research, high-altitude balloon science, motorsport, standing rigging, conductive textile and structural rehabilitation.
PBO is the strongest and stiffest of commercially available fibers used to repair and strengthen concrete and masonry structures in externally bonded composite systems.
In carbon fiber production, a fiber that results from a relatively low temperature (200–500°C) heat treatment in the presence of oxygen, which converts the precursor fiber, PAN or rayon, to an infusible fiber that is stable to further processing, we called it Pre-oxidized Fiber.
