Hi guys, I'm doing some infusion tests with carbon twill 3k at low cost and I have problems
because the result is always the same getting dry finish on the surface.

I tried some methods like closing the vacuum line and then making the piece rich in resin, but nothing, it's always the same ..

Resin pot line: 6mm full open, fast.
Test 1: 30 seconds
Test 2: 1 minute
Test 3: 1 minute 30 seconds
Test 4: 2 minutes
Test 5: 4 minutes
Test 6: 8 minutes

Always the same, dry spots.


Testing on glass, plain..
Infusion area: 25x30cm - Carbon area: 15cm x 20cm

Im using the entire vacuum infusion kit from easycomposites, but not:
-Carbon Fiber
-Vacuum bag.
-Peel ply
-Epoxy Resin A+B = 400cps.

Any comments will be appreciated, thank you.

Did the chemical release fix your problem?

Hi
Yes, I have solved the problem with the release agent, now I am using frekote 700-nc.
Would be great to be able to buy the Easy-Lease Chemical Release Agent but it is impossible, it can not be imported.
