Twaron is not Kevlar[edit]

As this entry notes, Kevlar is a registered trademark of E.I. Du Pont de Nemours and Co. Twaron is manufactured by Teijin Twaron, and is a different product, like Coke and Pepsi are different products. As Coke and Pepsi are both colas, Kevlar and Twaron are both aramid fibers. Kevlar, however, is not "also known as" Twaron; they are two competing products.

5 times as strong as steel?[edit]

This is debateable as there are many different types of steel. It could be between 3.31 and 77 times as strong, depending on your source of data. How about Dupont claim Kevlar is 5 times as strong as steel?

- Does it help that people say that its 5 times stronger weight for weight?


its a throw away comment as the type of strength isn't qualified like tensile or dynamic

It's imposible to be 5 times stronger than a good steel polyalloy. Maybe it's steel 5 times stronger than kevlar.


the picture[edit]

Applications,: Sporting goods[edit]

The first two paragraphs in this section list multiple unrelated items snd then these are followed by single-sentence entries per product.

Also, Kevlar is not often used to string tennis racquets, it use would be considered uncommon but still available as of 2015. — Preceding unsigned comment added by 160.94.167.79 (talk) 22:28, 17 March 2015 (UTC)


I've made it a bit better. The entire Applications section needs to be restructured, and is short references. Rwessel (talk) 09:41, 18 March 2015 (UTC)

Etymology[edit]

Any idea how the word "Kevlar" was created? Equinox (talk) 19:21, 10 September 2015 (UTC)

Needed Citations[edit]

I found potential references sources for the statement about use of Kevlar in bellows expansion joints in European Plastics News, Volume 9, 1982. Also in https://books.google.com/books?id=COgvEhUnFq8C&dq=kevlar+expansion+joint+bellows&lr=&source=gbs_navlinks_s p. 78 discusses rubber expansion joints, but does not mention Kevlar specifically, but p. 29-30 discussed Kevlar used in inflatable seals. A source for use in braided hoses is https://books.google.com/books?id=KQ5IAgAAQBAJ&dq=kevlar+braided+hose&lr=&source=gbs_navlinks_s, p. 349. Although I would rephrase to better reflect the sources.
