Kevlar and it's mechanical properties

[hexhunter]

hi, I'm making a small site for my coursework on Kevlar, it's uses in defense and it's mechanical properties, I've found that without a textbook or anything like that(our school's physics department is made up by a dep. head, a head of house and a new techer, so we have no head of phys.) it is hard to find the details and to recover the things we did at school.

does anyone know, or know a source for, information regarding Kevlar's mechanical properties(strength, stress, strain, youngs modulus) or just mechanical physics itself?

PS: cool new design

Try www.matweb.com, and search on Kevlar. There are several choices, so I recommend a sampling.

Hello,

Kevlar is a fascinating material with many unique properties that make it useful in a variety of applications, particularly in defense. Its mechanical properties are a key factor in its effectiveness and reliability.

Firstly, Kevlar has a very high tensile strength, meaning it is able to resist large amounts of pulling force before breaking. This makes it ideal for use in bulletproof vests and other protective gear.

In terms of stress and strain, Kevlar has a high resistance to both. Stress is the force applied to a material, while strain is the resulting deformation. Kevlar is able to withstand high levels of stress and maintain its shape and structural integrity, making it a valuable material in situations where it may be subjected to extreme forces.

Another important mechanical property of Kevlar is its Young's modulus, which measures the stiffness or rigidity of a material. Kevlar has a very high Young's modulus, meaning it is very rigid and difficult to stretch or compress. This property allows it to absorb and distribute impact energy, making it useful in applications such as body armor.

If you are looking for more information on Kevlar's mechanical properties, I would suggest checking out reputable scientific journals or websites, such as those from universities or research institutions. You can also consult with a physics teacher or expert in the field for more specific information.

I hope this helps and good luck with your coursework! And yes, the new design looks great.
