Different types of graphite...?

[irishcommodore15]

I was looking at the racquet compositions and noticed that there were three types of graphite:graphite(Babolat Pure Drive),high modulus graphite(Babolat AeroPro Drive, Volkl DNX racquets, etc), and ultra high modulus graphite(ProKennex Ionic Ki racquets). Any big differences between them?

Graphite has a very specific chemical definition, basically it consists of nothing but carbon atom sheets that stack on top of each other. The only element is carbon, except on the outer most layer.
However, purity can be an issue.

The higher the modulus, the stiffer the grade of graphite.

The higher the modulus, the stiffer the grade of graphite.

So the higher the modulus has more densly arranged carbon atoms. I really like the old school rackets with lower modulus graphite used in thicker weaves. The new rackets using higher modulus "hardened carbon" are stiffer and have thinner graphite weaves. Unfortunately, racket contact with the ground and baseline bashing caused the new school rackets to break much sooner. Graphite is really a very interesting structure.

You say tomato and I say toe-ma-toe:

Different manufacturers have a different name for different patented graphite materials. Wilson calls one such material Hyper Carbon. It's all graphite. The most important thing to remember is that different percentage composition materials yield a different FEEL. For example, a blended composition of 20% Kevlar and 80% graphite will have a more dampened (or dead) FEEL. 100% graphite is very lively. It is what I prefer most. nCoded Hyper Carbon refers to the filling in of gaps (with silicon) at the molecular level (nanotechnology) to provide more stability. Does is really work??? Is silicon really in there??? I don't know...I can't see atoms.
:neutral:

HyperCarbon is Wilson's brand name for it's grade of Ultra High Modulus Graphite.

Do you guys carry HP calculators in your pockets when you play tennis?

Not in my pocket, but in my free hand so that I can punch the keys with my thumb. It's a good thing I use a 1HBH. LOL

Real men use Texas Instruments.

real men carry those texas instruments graphing calculators in their pocket so they can play space invaders or super mario bros. at any given moment.

I've got both and much more in my old (13 years old actually) HP48 GX with 2 memory cards (1.2Mb total).

 

[Amone]

Wrong! Real men do advanced algebra in their head, hence not needing the calculator.

 

[Court_Jester]

Real men have no use for graphing calculators to do things like calculus and physics. Pen-and-paper is the way to do them and like Amone said, done in the head, too.

Forget the real men ...

"Smart" men copy ... and develop.

Hey Coach, do you really believe Wilson is preforming NanoTechnology to produce those nCode rackets ? If they can really change the graphite by infusing silicon molecules then they should be selling replacement material to Nasa to help the space program and the shuttle problems

 

[Davai]

Isn't it possible to make rackets the way Japanese swords used to be made?
They used to be cooled off very quickly so the air gets locked in the matrix thus making the sword stronger. Or is that how rackets are made already anyhow.

 

[freak-of-nature]

that certainly sounds interesting.

The racquet would be called nKatana or O3 Katana of mfil-katana...

lol

Hence the statement, I can't see atoms, so I don't know...hard to believe, especially since much of the so-called technological advancement turns out to be marketing. For example Prince triple threat technology is merely a sticker and not woven through and through at the 10:00 & 2:00 positions...titanium and liquidmetal racquets...how much titanium or liquid metal do you think is in each of those racquets, perhaps they were feather dusted with the material It sounds great in theory, and perhaps has truly been developed, but has each racquet been manufactured this way? I don't know.
