Hi,

Was wondering if anybody has any good suggestions to alternatives to carbon fiber and resin for testing setups. So that I am not wasting as much carbon and resin I am looking for a way to do a dry run.

I had thought maybe some kind of cheap material and a liquid that has a similar viscosity to the IN2 resin that EC sells.

I understand that the only real way to test is with the real materials but wonder if there would be any value in doing a test like this and if anybody on here does this?

Thanks for any input / ideas

Yeh just use fibreglass and perhaps an infusion polyester for a cheap resin. The only downside is polyester/vinyl esters infuse slightly differently to epoxies, but they are certainly close enough to just get the hang of the process.

You can always make some glass fibre parts to learn to get the infusion setup right. This has the added benefit that you will clearly see the porosity and can very easily spot defects. 
Orher than that i would really recommend sticking to the same materials as there won't be much that transfers over.

Right ok I think the fibreglass suggesting is worth giving a thought, but I had I’m mind something cheaper like a textile fabric and wasn’t planning to use a resin that would set. Had thought it could have been interesting to learn about the way the resin flows in infusions.

Maybe I’ll need to bite the bullet. Totally understand the only way to find out is by using the real materials, or close to.

Thanks for your response

Yeah thanks again the the extra suggestion there. I didn’t so much need anything that would set, but just to get an idea about the flow while it’s live.
