For the PPP: Frame: Toray M30GC Shaft: Toray 46T aka 1000T For the Thunder: Frame: Toray M30GC Shaft; Toray M30GC
i found the website for Toray. looks like Japanese fiber, good stuff. http://www.torayusa.com/cfa/product.html but i cannot find the exact matching model that you listed. there are M30G and M30C. but not GC. there is M46J but not 46T. there is also T1000G but no 1000T.
thanks for the info. Hi-Qua Indonesia also has so-called RCX Personal Edition which will be designed based on personal requirement, and the material is 40T super nano carbon and nano resin.
I believe these are standard modulus fiber (frame) and medium modulus fibers (shaft). These have great modulus strength (TS) but relatively poor tensile modulus (Youngs modulus or TM)). Toray's nomenclature with M and low numbers like 30 to 40 are medium tensile modulus but high tensile strength, with low probably belonging to the standard modulus category. The T means high strength, the larger the number (T1000), but low or medium modulus. However, you can overcome the lack of high youngs modulus, by using a box shape as well as very wide cross-section frames, to some extent. The flip side is a slower racquet because of increased air resistance in the swing direction of a racquet. Try to get MJ65J extremely high youngs modulus carbon fiber from Toray directly and then get a manufacturer who is prepared to do some research to use this high-tech fiber. It has extremely high youngs modulus but only so-so tensile strength. Most racquet manufacturers do not buy MJ65 because of very high costs.
The Toray info above is for its generic graphite. I believe there are slight modifications made to the generic graphite to accommodate badminton needs. In addition, the names could be slightly altered or changed.

i was told that Yonex uses at high as M30 for their top of the line rackets. the high end Jpsee i received as samples are M40 grade. they claim a M46 grade model is coming soon. i wonder how Yonex can be using M30 graphite but at the same time claim it is High Modulus.
Well, it can be if you're talking reality, relative to other rackets, not in pure technical terms. I will explain... ...I've been told (within a reasonable cost) the strongest (able to take high tension) graphite for a frame is M30GC and the "best" graphite for the shaft is 46T aka 1000T. In technical terms, they are not high or ultra high modulus, but they are high or ultra high relative to other badminton rackets. So, it's all relative. Either that or Yonex figured the masses would not understand graphite. Maybe they should rename it strong or very strong modulus graphite.
I have no way to confirm or dispute what Kwun or Panda the Big Square Butt post till next time I visit the Evil Empire Palace... They sound OK to me at this point...

Hey Dink, u got an extra prototype for Viper to test? I'll be at GG rec center Sunday. I'm currently testing the Yonex Nanospeed 9900.
Toray's M series start from M30 to M65J. M46 is usually used in high end racquets. The best grades for racquets are their M55J, M60J and M65J, but these may not be economically viable due to much higher costs.
According to the Toray site, M30 and T1000 are intermediate modulus graphites: http://www.torayusa.com/cfa/intermediatemodulus.html You have declared yourself the expert on graphite, can you explain what 40-ton graphite means? So far as I can tell (internet search) it is a term that is only used by badminton racquet companies. If I had to guess they are referring to the tensile modulus (even though the units for that are msi meaning millions of pounds per square inch which is about 500 times greater than a ton (2000ish pounds)). If so, then the graphites in question are 42.7 msi which would make them relatively high in the badminton world. That is very funny! DinkALot posted about a racquet that can take a 40lb string tension and might possibly be strong enough to resist the racquet snapping force of DinkALot's smash. And you suggest that he use an extremely high modulus graphite with, "only so-so tensile strength!"
BTW, there are racquets that is rated by the manufacturer to take up to 40lbs. http://www.fleetsports.com.tw/02/canewsmenu1.asp?lvname=WOVEN%A8t%A6C The Woven Fleet 1000/999/888 in 2U specs are supposed to take the high tension.
My take on racquets is to go for the highest tensile modulus like M65J which has a rather modest tensile strength of 559 ksi. This racquet can be strung upto 36lbs but you will have to take care to avoid clashes, because its high stiffness is relatively brittle. Not all fiber manufacturers specs are the same. Toray is by far the most conservative.
I don't think any of Toray's M series fibers have a tensile modulus lower than 45 msi. The M30 could be about 45msi, M35J 49.8 msi, and M40 about 57 msi. These would be considered lower grades for really top racquets. Some years ago I had about 30 racquets with tapered shaft made by a friend who owns a racquet factory. He claimed he used M60J. Although it played well, I never really believe he actually used M60J. Some of the carbon fibers made by other fiber manufacturers claim even much higher specs than Toray's M series, but I have tried some and they are nowhere nearly half as good as Toray's.
