Most likely Arctic's Bio Foam, Super Sap or RR's Bio Resin and Basalt.
That which can be assorted without evidence was read in an illegal magazine.
Good guess on my part. I'll stick with RR though. Super Sap will eventually go belly up. Their customer service sucks. Gave me the run around for no reason. If I need "Green"; RR's "Bio" will do fine. Better price and can be bought easily at outlets like FoamEZ. Lowel
Just wanted to mention biomid fiber,
I have no experience with this material, but read about it here in the forum some years back.
It still exists and seems to be a sandable alternative to glass.
I am pretty sure that your problem with glass is in the sizing, not the glass itself. So you could probably try another brand.
Hi everyone, it's been a while.
Here's three fabrics from Glasser Mills. The left two work with epoxy. One was Nylon 6,6, one was recycled soda bottles. Ask about colors, and weights. They will sell cut yardage if they have it. If you want a specific color, your going to buy an entire roll. That's expensive.
The right sample had a finish on it that made it like peel ply. Glasser mills in New York is a great resource.
Nylon 6,6 bonds with epoxy. Nylon doesn't, so you have to be careful of the chemistry of the fabric. Most sources will sell you a clothing fabric that has water repellant. Those don't work at all. Same with flag fabrics.
Elongation thoughts. Elongation is good. That's why they dent and don't ding. Control your stiffness and elasticity with a second layer of fiberglass, carbon, twaron, Kevlar, stringers, deck channels or whatever.
The fabrics are usually a tight weave, so they can be hard to wet out and drape. Don't wrap the rails much with Nylon, just split it mid rail, and use fiberglass tape or a second layer of fiberglass over for a hand lam. You really want to saturate the Nylon 6,6 on a wet out table.
I've done about half a dozen build threads here in the past 10 years, where I went into tons of details
i was hoping you would chime in on this topic, I've spent a lot of time seeking out your posts in the archive and your findings. Thanks for doing the experiments and sharing your wisdom
It's all about fun
You're the man. Glad you jumped in on this. I don't think there is anyone around this sight or even in the "Industry" who knows more about these fabrics and their application to surfboards than you. Lowel
PET (soda bottle) is used for longtime in some composits that need toughness for cheap. Called xylon or diolen or... It can be found in open plain wave specific for composits use, easier to wet. Inegra which is PP fiber, is the plastic fiber of this family (poor man Kevlar) that's in the light for composits actually.
I just ordered 30 yards of 60" wide white (optical brightener) nylon 6,6. In 420 denier. Enough for a dozen or so boards. Let me know if anybody wants to share some.
I'm interested! Where did you get it from and how expensive is the stuff? Been resistant to ordering nylon as result of not finding the 6,6 variant
