problem with surfacing veil

#1

Well im new here and there is a great deal of information here. Well im a newbie at this and ive come aross a problem. We bulit a hood for a racecar that are for dragrace only so we use carbon for weight saving only. the hood consist of duratec primer sprayed in the mold then we apply the veil just to control carbon print in the heat, Next we applyed 2 layers of 3k and then a inner layer of 2mm soric mat. Outer flange has kevaler and then we finish with one layer of 6k. the whole prosses seem to go very well but now that i have the hood out of mold i noticed some bubbles and i cut them out and looks like the veil did no take to the carbon. Is this veil a problem? or is leaving a vaccum pump run to long drying out the part? Any ideas

Thanks,Mike

Do you have a picture?

is this wet bagging, or infusion?

how much vacuum?

Infusion, I think we might know the problem, we only had vacuum run for 7 hours and then we lost vacuum. Could that be the problem? I know it was 66 degrees were we are. I used huntsman resion and pot life is 1 1/2 hours at 77 so it had to cure way slow I’m guessing. 28 vac

Try to up the vacuum before and during infusion. This does help fight air bubbles.
