Hi, iv made a couple of small infusion part about 6inch long by 2inch.
Although the weave is nice and straight and no imperfections it isn't compressed nicely and can see gaps in the weave.
Mould was gel coated and left to cure, and then carbon laid with a mist of 3m 77 spray.
Also tried pro finish carbon.
Im thinking it's either glue on the carbon stopping it compressing in to place, or infused to fast because it's so small.
Resin is In2 fast
Any ideas.
Thanks

I've encountered a similar issue where the crowns of the weaves weren't flattened, like they are on most high-end OEM automotive carbon. First time this happened, the resin feed went too long before it was clamped off. MTI hose was used so the excess resin couldn't flow out. This seemed to reduce the vacuum pressure in the bag. this resulted in a very nice surface finish but no tow compression. Next attempt, the resin feed was shut off a few minutes prior to full wet-out. the result was flattened fiber...just what i was looking for.
Hope that helps!
