So, is it about energy absorption, or energy transfer?

 The basic laws of physics dictate that any action is met with an equal, but opposite, reaction, so it has to have something to do with what happens upon impact.

 Maybe somebody has the info on the C. O. R. numbers as compared to a "regular" outer core wrap material with the same shell material? Maybe they've found a way to maximize that.

Absorption and transfer of energy are 2 sides of the same coin. If the carbon fiber absorbs xx% the energy applied, that percentage of the total energy applied cannot, is not transferred. COR is all about transferred energy.

FYI Carbon fiber is used in the stereo reproduction industry and others to absorb energy; i.e. to insure it is not transferred. I have some carbon fiber platforms under CD players and other pieces of electronics for just that purpose; they seem to do that job.

Charlest, you seem to have a pretty good understanding about energy absorption/energy transfer and how that may effect pin carry.  So in your opinion is what they talked about in the video for real and can it actually make this ball different in energy retention and pin carry from any prior balls manufactured.  Or is it just some more marketing hype to sell more balls? 

I know what I use Carbon fiber for in my audio/stereo set-up: to absorb unwanted vibrations. I cannot understand how this capability of carbon fiber is applied to a core's construction in such a way as to increase the response of a ball hitting pins. From what I understand of carbon fiber, it apparent effect should be the opposite of what is desirable. Maybe my understanding of CF does not apply to ball cores. I remain perplexed at the current explanation.

"Viscoelasticity" is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation.

In the video they don't say what the material is they are adding to the ball. They don't mention carbon fiber at all.

As I said, I don't know how they're applying Carbon Fiber in this case.

There's nothing saying they are using Carbon Fiber in the first place.

I guess I better go listen to that video again.
Yes, apologies, they don't use the phrase, "Carbon Fiber".
They do bandy some techy words about without explaining them, like "Cross linked polymer matrix"; but the concept of vibration absorption is still applicable, whether it's Carbon Fiber, like Hammer uses, Sorbothane or Iso-Damp. They all absorb vibration to an extreme degree. Most don't bounce as in that experiment.

I still don't understand how when applying this to a core, it provides a greater COR.

I'm just guessing, but I bet you read the post on BBE where BSoares said: " If they don't, then it's just a marketing gimmick like carbon fiber in the cover. " that Hammer did.

and that's where you picked it up. That's the only place I saw CF mentioned but it was in reference to Hammers stuff.

I do remember Soares, but I can't say for sure that was the reason I picked up on "carbon fiber". I'd really love to know what the chemistry involved in this process is.

Here we go Happy Sad Balls

Yup, same difference as what the Columbia tape showed.
"Sad Balls" are made from Nosorex. Here's a quote from one source:
"You can see that one bounces and one stays on the ground. Why? They are made of two different materials: Polychloropene (trade name Neoprene) and Polynorbornene (trade name Norsorex). Both feel nice and rubbery and are about the same density. Both are pretty elastic – when you squish them, they return to shape nicely. Polychloropene is very bouncy – it wants to snap back to shape quickly. Polynorbornene is an impact-absorbing material that can be used for things like shoe insoles and high-tech golf balls."

here's one place where you can buy them:
