Twaron is not Kevlar
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?
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 ultraviolet component of sunlight degrades and decomposes Kevlar, a problem known as UV degradation, and so it is rarely used outdoors without protection against sunlight.

The History section calls Kwolek's discovery of Kevlar's resilience, "accidental." However, it also describes Kwolek's process of recognizing properties she was looking for in a substance and then pursuing examination of that substance based on that observation, which led to the discovery the section discussed. Even if Kwolek was not expecting the result she got, calling the discovery, "accidental" is questionable, given that the discovery was the result of intentional examination of a substance that displayed properties Kwolek's team was looking for.
Applications,: Sporting goods
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 18.104.22.168 (talk) 22:28, 17 March 2015 (UTC)
