I felt a couple up at the local shop a month or two ago and they were bricks. I forgot to look to see if they were Team Light. They may have been early versions and were Ultra Light.
I don’t see how powder would increase tensile strength as opposed to fiber. I could see, maybe, some increase in compressive strength. Maybe. There are a lot of carbon powders on the market and all boast of adding strength but I couldn’t find a single scientific study analyzing or comparing strength properties. And remember, the powder is changing the resin matrix, not the fiber. They are still using glass.
Also, I would object to the “eco” moniker for anything carbon fiber. It is has the most energy intensive manufacturing process of any surfboard material, hence the high cost. He states that they are making the powder. My guess is that they are using the off cuts, which means they are utilizing the waste and not recycling. That’s commendable but not really recycling.
I read a study about recycling carbon fiber and it is possible but extremely complex. You can imagine separating the carbon fiber from the resin matrix. Mechanical separation produces a product with far inferior mechanical properties. Chemical recycling produces an analogous product but it is a costly and highly toxic process. Then there s thermo recycling which is again energy intensive and toxic.

But again, this study is talking about carbon fibers. If someone can find me an analysis of the powders please share.
So, yeah, I’m skeptical, but would be glad to be proven wrong.

Recycling Carbon Fiber from Carbon Fiber-Reinforced Polymer and Its Reuse in Photocatalysis: A Review
Driven by various environmental and economic factors, it is emerging to adopt an efficient and sustainable strategy to recycle carbon fibers (rCFs) from carbon fiber-reinforced polymer (CFRP) wastes and reuse them in high-value applications. This review ...

I know in the wooden kayak world you can mix carbon fiber powder with epoxy to make a super durable coating that protects the hull from rock damage. It gets applied over the glass on a kayak. Have you ever used West System 403 Microfibers with epoxy? Even a little bit of that stuff mixed with epoxy dramatically increases its strength. I use it on all of my fin box and leash plug installs.I don’t see how powder would increase tensile strength as opposed to fiber. I could see, maybe, some increase in compressive strength. Maybe.

Even West Systems does not advertise any strength properties for that filler. You'd think if it ADDED strength that would be something they would highlight. Anecdotal info is valid but I would be interested in any scientific data.

Pricey stuff. Some Logo overlap???

Even pricier. This site gives some #s but doesn't say what the powder was mixed with???? Or how testing was done.

I did find some strength numbers, but again they are supplied by the vendor with no info about the test. I'm always curious what what the matrix (eg- resin) being used is? Well, actually I screen shot this bit because this one does say "single filament" strength, which implies independent of the matrix. But to me pulverized is not the same as filaments.
I was going to at the CI shop the other day but I’m on their sh!t list for putting my thumb through a Bonzer Biscut so I’m only allowed to monkey grip their boards now.Did you finger ding it checking out the glass job?
