The Ec and Ep for the Nittaku Acoustic Inner look very low – lower than standard Acoustic. Is that correct?
LikeLike
Those values are correct. I think that one reason it its thin construction. (Just 5.4mm.)
LikeLike
I forgot to mention. One important reason why the elasticity of Acoustic Carbon Inner is its center layer.
In general, the center layer of inner fiber blade is harder than the center layer of outer fiber blades. If the same wood as the center layer of outer fiber blade is used for the center layer of inner fiber blade, the elasticity level becomes very low. In that case it makers increases the thickness of blade to compensate for the loss of elasticity. However, Acoustic Carbon Inner is same or even thinner than Acoustic Carbon (outer).
Another example of inner fiber blade whose center layer is that for outer fiber blade is Tibhar Stratus Samsonov Carbon. That is the reason why Stratus Samsonov Carbon is not much elastic.

Hi 🙂
i want to ask you about similar blade like nittaku acoustic inner carbon, in fact the blade is nittaku kasumi eternity (it is limited edition)!
they say that this blade have identical structure like acoustic inner but its thicness is 6mm..
i wonder if it will be alot more elastic?!
and how it will feel, what you think?.
thank you in advance.
LikeLike
Then Kasumi Eternity is different blade from Acoustic Carbon Inner.
The thickness of Acoustic Carbon Inner is just 5.4mm. And, that makes Acoustic Carbon Inner slower than expected. (But, thanks to carbon fiber, you’ll not feel it slow when you smash with it.)
Kasumi Eternity will be much stiffer and much more elastic than Acoustic Carbon Inner. I expect that Ep will be higher than 1.8, and Vp will be higher than 1.2.

Both seems on the paper very similar , do you confirm ?
LikeLike
Although they look similar, there is significant difference between those two.
The artificial material of Waldner Senso Carbon is Carbon Fleece which is tissue-shaped carbon fiber. But, the artificial material of Acoustic Carbon Inner is woven carbon fiber.
Therefore it seems likely that the similarity between the two blades is merely a result of coincidence. Or, it could be one of the evidences that the role of the artificial material is greatly reduced in inner fiber constructions.

On paper they look very similar. But in real world testing Korbel SK7 has much more power and feels much more harder and stiffer. But I must to mention that both setups have different rubbers and unknown weights of blades itself.
LikeLike
I have many pcs. of Korbel SK7, and the thickness of Korbel SK7 isn’t much different from much heavier ‘SK7’. Interestingly, ‘Korbel SK7’ I have are much softer and much less elastic than original ‘SK7’ whose construction looks almost identical. Probably that is because of the difference in weight range.
But, the blade can produce more power although there isn’t noticeable differences in elasticity if that blade is thicker than the other one under comparison. That is concerned with Ec.
BTW, both of the Ep and the Ec of ‘Korbel SK7’ are noticeably higher than those of ‘Diva’. Difference between 1.48 and 1.55 isn’t ignorable. It is sufficiently meaningful difference, and ‘Korbel SK7’ is noticeably more elastic than ‘Diva’.
The only one common feature between ‘Korbel SK7’ and ‘Diva’ is the feeling of hugging ball because the Ec/Eps of those two are identical to each other.

It is old one whose name doesn’t include ‘Layer’.
New ‘InnerForce Layer ZLF’ is a different blade from old ‘InnerForce ZLF’, so it should be measured separately. I couldn’t have get the sample of new ‘Inner Force Layer ZLF’ yet.

I was surprised by Ep=1.73 and Vl/VP=0.94 indices. I had Liu Shiwen ZLF (2013-2014) 89gr. it was quite thin(5.4-5.5mm) and had low frequency, around 1100 hz. And i suppose that 1100hz it is around Ep=1.3. May be my copy was too old and dried. Actualy, i think, it is impossible to find modern analog for old Innerforce ZLF/Liu Shiwen. May be someone can give me advice?

As i know about Butterfly inner ZLF:
I didnt like Innerforce layer ALC S. thats why i dont want to try modern Innerforce layer ZLF and 5.3mm its to thin. i suppose Primorac Off-(japan) must be better for me if i need OFF- blade.

The center layer of Fukuhara Pro ZLF is Ayous. It is based on old InnerForce ZLF. (The second layer is Ayous if my memory is correct. If it is Limba, the Vl of InnerForce ZLF will be much higher.) And, the second layer of InnerForce Layer ZLF is Spruce.
By the way, I think that IF Layer ZLF will be much different from IF Layer ALC.S. The feeling of ZLF is totally different from ALC. So, I don’t recommend predicting the character of IF Layer ZLF from the experience of IF Layer ALC.S.
LikeLike
1100 Hz is probably the 4th natural frequendy. And, it isn’t directly concerned with Ep. (Although it affects a portion of Ep.) The most important frequency that affects Ep is the first frequency which is related with bending distortion.
So, you’d better not predict Ep from that frequency. That 4th frequency can be higher or lower.

Thank you for comment. Walnder 89 Champion is on my list. But, I’m not sure whether I can get it in short time or not. (I’ll once ask Donic distributor.)
For the calculation of the parameters, I measure the natural frequencies of blade. But, the frequency itself can’t explain the base speed. And, if you just measure one frequency among many natural frequencies, that data just show us the information about ‘sound’. So I have to gather more information of blade including frequencies and then calculate.
