Hi Modulus

jsevalle · 10-08-2002, 08:16 AM

What is Hi Modulus, it's used in rackets right? but what is it??

*kwun* · 10-08-2002, 08:49 AM

modulus = stress/strain.

it is a measure for stiffness.

Hi Modulus... like you know... Hi Bob or Hi Jane.

... okay I didn't get enough sleep and I'm bored to boot

modious · 10-08-2002, 10:26 PM

yes, I almost thought somebody wanted to know me or something!! (Because some pple spell my nick that way somtimes....)

here is a good quote for your question

"Modulus is nothing but a fancy word for stiffness. It's a measure of how much a material will stretch if you hang a weight from the end of it. If it stretches a lot, it has a low modulus; a little, it has a high (Hi) modulus. That's pulling stiffness. There is also flex or bending stiffness. That's measured by supporting both ends of a material and putting a weight in the middle, and measuring how much it bends. Again, a material that bends very little has a high flex modulus. It's one of those confusing things where a little is a lot, and a lot is a little."

Modulus says 'hi' to you too.

I agree to this quote, but to add my two cents worth, Modulus = The Constant factor or the ratio. Look it up in the dictionary and you will see the same if not similar explanation. The HI part in the modulus is obvious therefore. So therefore, if the meaning of Modulus is true, then Hi Modulas would most certainly have to mean a higher level of the racquet maintaining it's shape in a smash for example. I'm not telling you that I am 100% right on this. I am just using the laws of physics and throwing in my 2 cents worth. I would stand corrected if I am told otherwise. So this is something that I would like to know more about too. But for now, the truth is in the Oxford English Dictionary folks. I hear that you can have higher stringing tension with this type of racquet. Mine is a Carlton Airblade 2000. Sweet racquet.

By the way, does "Titanium Hi-Modulus Graphite" mean it has both materials?

Great article here.

Nice website! It has detail explain about hi modulus graphite. But what abot woven? I have seen some racket made of woven. What is it?

I believe that woven graphite is where they weave the graphite fibres instead of layering them at 90 degrees. Obviously weaving the fibres takes more effort, hence the higher cost, but based on the article, you can see why they can be stronger than conventional graphite fibres.

From the website, I know that the lay-up is very important in manufacture the racket. They use resin to glue the layers together. And the different layer has differnt angle. But from the picture you post, the woven seem to cut the layers into stripes and weave together ? Would you give me more information.

jsevalle · 03-18-2003, 06:50 AM

So that's why some rackets are expensive

Sorry, I don't know any more. Your guess is as good as mine and it seems that WOVEN graphite also have different classes depending on how they weave the graphites plus the addition of any other materials (e.g. Prince talked about their Triple Threat which consist of copper, titanium & copper).

I've not heard of copper being used in a titanium mesh before... but I guess that could explain why my ti mesh is gold-coloured. (here: http://badmintonforum.com/vb/showthr...&threadid=9210) Any idea what copper is supposed to do? Seems like it's just adding weight to the head since copper is neither strong nor stiff.

Hey guys i'm new to this place, and i just got a carlton megagflex f2 raquet, on the frame it says high modulus graphite, i'm just wondering, if this another good raquet that is meant to be for pros, or is it just me??
