Which is better, high strength and high modulus polyethylene fiber or aramid fiber?

Aramid (Nomex is a kind of aramid, is benzene dicarbonyl benzene diamine), is a new type of high-tech synthetic fibers, with ultra-high strength, high modulus and high temperature, acid and alkali resistance, lightweight, insulation, aging, life cycle and other excellent properties, widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and other fields.

Aramid is known as "polyphenylene dicarbonyl benzene diamine", Aramid fiber in English (Teijin Aramid's trade name is Twaron DuPont's trade name is Kevlar), is a new type of high-tech synthetic fibers, with ultra-high strength, high modulus, and resistance to high temperatures, acid and alkali, lightweight and other excellent performance, its strength is 5 to 6 times the steel wire, modulus of steel wire or glass fibers 2 to 3 times, and its strength is 5 to 6 times, and modulus is 2 to 3 times the steel wire or glass fibers, and its strength is 2 to 3 times the steel wire or glass fibers. Its strength is 5 to 6 times that of steel wire, modulus is 2 to 3 times that of steel wire or glass fiber, toughness is 2 times that of steel wire, and its weight is only about 1/5 of steel wire, and it does not decompose or melt under the temperature of 560 degrees. It has good insulation and anti-aging properties and has a long life cycle. The discovery of aramid is considered a very important historical process in the materials world.

High-strength, high-modulus polyethylene fiber composite line (English full name: Ultra High Molecular Weight Polyethylene Fiber Compositeline, abbreviated as PE-C), also known as PE-line or ultra-high molecular weight polyethylene fiber composite line, is the world's highest specific strength, specific modulus and composite rate than the composite line, a new generation of composite materials. Composite line, is a new generation of composite materials.

High-strength, high-mode polyethylene fiber composite line (PE-C), as the name implies, it consists of high-strength, high-mode polyethylene fibers composite by a special process and a new type of matrix resin, high-strength, high-mode polyethylene (UHMWPE) is a kind of polyethylene material (PE). High strength and high modulus polyethylene fiber is the world's highest specific strength, specific modulus of the fiber. PE-C composite rate of up to 90%, and by a special process and a new type of composite material made of composite line composite strength is high, to improve the transfer of fiber stress. The original high-strength high-modulus polyethylene fibers in the absence of composite case compacted into a bundle due to the irregular shape of the fiber monofilament cross-section fiber compactness is generally only 85% or so, there is 15% of the void rate. Composite rate of 85% of high-strength, high-modulus polyethylene fiber composite line to increase the strength without increasing the thickness of the original fiber (volume). In high-performance composites show great advantages.
