Glaser Mills. Factory direct. It's about $6 a yard.
Nylon was trademark of polyamide 6.6 by dupont de Nemours around 1935... Now free Mark used for PA6.6. Often coated because don't like water so much.
Those plastic fibers have poor adhesion with glues by themselves when they are coated even more that's sell as peel ply in composits world...
Need no coated and "open wave" to be use in composits, you want fiber to be embedded in resin...
From talking with the guy at Glaser, the recycled soda bottle fabric used to be finished with a starch based finish, that bonded really well with epoxy. They changed that to a different finish, that won't bond. If you go with that fabric from them, only use the unfinished. For small purchases, it's a lot of luck, since you're getting the remnant from a larger production run.
The OP started not wanting to get into vacuum bagging. I don't think most of the plastics are going to work without vacuum bagging. Some probably won't even work without a wet-out table.
gonna reach out soon about maybe grabbing some of that fabric from you
wanted to ask about muslin cloth, I often see it at fabric stores with a nice loose weave and it's cheap, any experiences? Soak up too much resin or not strong enough?
I've used hemp for inlays, deck patches and tail patches. Hemp is supposedly as strong as wood for its weight. But I've always covered it with a layer of fiberglass.
Heres a few eco materials we have worked on to get them right for Surfboard laminations
With our hemp product we are just about to launch a 100% hemp cloth (about a month away) - we work with the hemp farmers in the Hunter valley nsw Australia to get the raw material - once the hemp seeds are harvested the plant is taken out and we use these plants to make our hemp yarn then woven into a 4oz cloth
All these cloths are fine for hand lam and all have been tested well and truely
Hi OP, I struggle to believe that you are properly allergic to glass fibre other than normal itchiness. Glass fibre is pretty much the same stuff you get in bottles and drinking glass so I reckon you would have noticed previously. If you were getting a reaction on handling glass fibre prior to any lamination it could be possible that it is the sizing that is applied to glass fibres that you could be allergic to. This is a chemical that stops the tows falling apart during manufacture and weaving. Old fashioned Levi's used to make me itch like mad till I'd washed them. If you know the brand of fibre an email to their tech support could be well worthwhile. The other potential issue this raises is that other fibres, such as carbon or hemp, may also be sized with same chemical so probably worth investigating.
I was thinking similar. Other than foiling fins, when do you ever sand fiberglass. If you hit the cloth, stop because you've gone to far.
The nylons I use don't sand at all, but turn to fuzz.
Did a doctor tell you about your allergy? Are you using epoxy? Epoxy does cause a reaction in some people who get too much on themselves.
