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.

Thanks for all your hard work! Since you’ve been posting Yasaka equipment recently, one blade I’d like to see analyzed is the Yasaka Extra Offensive Power 7.
LikeLike
Hmmmm …… I don’t have the sample of Yasaka Extra Offensive 7 Power. But, I will put it in my check list. It will be first considered when I get next Yasaka samples. (But, I don’t know when.) 🙂

Hmmmmmm …….. I don’t have the sample of that blade. And, it will be difficult for me to get TP_Ligna series.
