That's better, kevlar fiber or pe fiber within the cloth?

First, supply the challenge a brief introduction to aramid and pe.

1. aramid fiber gadget aramid, additionally known as kevlar (the chemical name is phthalamide) become born in the overdue 1960s. it's far a brand new kind of high-tech synthetic fiber, which has high temperature resistance, acid and alkali resistance. , light weight, excessive power and other benefits, has been widely utilized in bullet-evidence shielding device, creation and electronic system and other fields.

However aramid additionally has two fatal shortcomings:

1) it's going to degrade whilst encountering ultraviolet rays; it is simple to hydrolyze, although it's miles stored in a dry environment, it will take in moisture inside the air and gradually hydrolyze.

2.Therefore, aramid bulletproof inserts and bulletproof vests are not suitable for long-term use in robust ultraviolet and humid environments, if you want to significantly lessen their defensive overall performance and carrier existence. further, the poor stability and short lifestyles of aramid additionally restriction the similarly application of aramid in the area of bulletproof.

3.The charge of amazing aramid is likewise higher than that of pe, which can be 30% to 50% greater. at present, bulletproof products the usage of aramid have gradually reduced and begun to be replaced through pe bulletproof products. until it is in a unique environment or has unique requirements, such as the excessive temperature of the center east, it is endorsed to apply pe material bulletproof system.

4. pe cited earlier than in pe fiber system truely refers to uhmw-pe, which is ultra-excessive molecular weight polyethylene. it is a excessive-overall performance organic fiber evolved inside the early 1980s, and is referred to as the arena today collectively with carbon fiber and aramid. 3 excessive-tech fibers. the plastic baggage used in our daily lifestyles are genuinely polyethylene merchandise, which have amazing excessive balance and are extraordinarily hard to degrade, which causes extreme environm
