Which is better, high-strength and high-modulus polyolefin fiber or aramid fiber

Aramid (Nomex is a type of aramid, which is phenylenediamide phthalamide), is a new type of high-tech synthetic fiber with ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, and insulation
It is widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and other fields.

The full name of aramid fiber is "polyphthalamide phenylene diamide", which is Aramid fiber in English (the trade name of Teijin Aramid is Twaron, and the trade name of DuPont is Kevlar). It is a new type of high-tech synthetic fiber.
Fiber, with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, etc. Its strength is 5-6 times that of steel wire, and its modulus is 2-3 times that of steel wire or glass fiber.
It is twice that of steel wire, but its weight is only about 1/5 of that of steel wire. It does not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging performance, and has a long life cycle
Expect. The discovery of aramid fiber is considered to be a very important historical process in the material industry.

High-strength and high-modulus polyethylene fiber composite line (English full name: Ultra High Molecular Weight Polyethylene Fiber Compositeline, referred to as PE-C), also known as PE line or ultra
High molecular weight polyethylene fiber composite thread is the composite thread with the highest specific strength, specific modulus and specific composite rate in the world at present, and it is a new generation of composite materials.

High-strength and high-modulus polyethylene fiber composite line (PE-C), as the name implies, it is made of high-strength and high-modulus polyethylene fiber through special technology and new matrix resin composite, high-strength and high-modulus polyethylene (UHM
WPE) is a type of polyethylene material (PE). High-strength and high-modulus polyolefin fiber is the fiber with the highest specific strength and specific modulus in the world. The composite rate of PE-C is as high as 90%, and the special process and new
The composite wire made of type composite material has high composite strength and improves the transmission of fiber stress. The original high-strength high-modulus polyethylene fiber is densely bundled without compounding due to the irregular cross-section of the fiber monofilament
The density of fiber-like fibers is generally only about 85%, with a porosity of 15%. The high-strength and high-modulus polyolefin fiber composite line with a composite rate of 85% increases the strength without increasing the thickness of the fibrils (volume
product). It shows great advantages in high-performance composite materials.
