Hi,
This is my result of several attempt of resin infusion. For the first time, i'm having quite a lot of voids on the surface. On second and third try, i have slowed down the resin, and clamp the vac line first then after a minute later i clamp the resin feed line, but still having the problem.
The part that i'm working on is approx. 1M x 1M. Its a car fender.
I'm using infusion epoxy resin from Axson (epolam 5015). The mold also made from Axson tooling gelcoat. In my country, temperature is not an issue even at night.
i'm able to pull full vac and there are no leak after i left it for 1 hour. the carbon i use is 650gsm from EC. Total time to infuse is less than 15 min.
You guys have any idea?

Air in the resin should only cause pin holes, this is totally dry.
