Fibre easier to work with, less fluffy?

General Discussion
1

I want to experiement with fibre.

I wondered if there’s anything with a weave easier to work with - something that stays together more when you cut it instead of ending up with fluffy bit stuck everywhere? 

S-Glass? Volan? Some kind of knitted fabric? Have you worked with anything like this? 

(carbon fibre is probably good but too expensive for testing)

edit:

Also, just to avoid creating a new thread… I just want to check… 

can you take Araldite poly resin and add a UV hardener from another manufactuer? Or do you have to get the 2 from the same source? The reason I ask is that this can subtantially reduce my shipping costs by just bringing in the UV hardener

Never heard of that brand of Poly Resin.  Enlighten me.  Use good long blades scissors or Electric scissors to avoid wravels at the lap.  Four ounce is extremely easy to work with.  Otherwise Nylon.   Work on improving your skills and improving your methodology rather than searching the lazy man’s method.

Well the experiment I’m going to try is tensioning the fabric over areas without any support. Awkward but not impossible with a fabric that unravels.
I might just got with veneer but fabric is more efficient and I want to check to see if carbon fibre is the only one to behave this way.

Araldite is a cheap and old style resin but it’s easier to get without an import license. Just prototyping cheap and quick with uv hardener

Gotcha.  Understood.  I’m thinking Nylon or two ounce E.

I guess that to find nylon fibre I see sanded have nylextra and cerex but they don’t ship many places so I have to find another source
Jute looks interesting too.

Most of these designed to go under a normal fibre layer… I’d like to see if it’s possible to reduce that step even at cost of quality

what is the performance goal you have in mind ?

… You want to set the fabric under tension right?

whats your goal?

cheers

Try cutting some holes in the wood so that it’s literally just fibre and resin keeping the water out

Nylon is everywhere. It’s what flags are made of. Ever color of the rainbow. www.beaconfabric.com www.Sailrite.com www.Dogbooties.com
Just make sure it is uncoated.

Yeah that’s the problem. All the nylon I find is generally aimed at making bags… if it’s waterproof how is the resin going to penetrate? I’m clicking through all these links and everything is intended as waterproof?

There must be a word we’re missing to find the stuff intended for glassing:

edit:

Just found this from some random on a forum… not sure if true but if so then the idea could be a red herring:

“Nylon develops strength at high elongation where the resin bond is lost and the laminate destroyed.” hmm… I guess fishing line stretches…

…and so only way to reduce fibre wieght before carbon cost remains kevlar… or kevlar blend to reduce some cost

When I feel the weight of fiber it seems heavy. On a wooden board perhaps it’s not needed… but then the question is the thickness of the wood… and what to waterproof it with… just layer on Titebond or poly resin which can crack… or go with epoxy and then it feels like a waste of the wood since if you go with epoxy why not match that with fibre for a nice composite… hmm…

I’m aiming for firewire FST strength and not more… with no more than 1kg extra weight for a 6’ board ( sorry for the F word )

It’s called dacron and the idea is already a thing. Will post a thr ad once built

Aerialite have a cloth specifically designed for people like me :stuck_out_tongue: there’s also biaxial cloth. plenty of options - I’m not crazy!
