Hello,
I have an issue with my hand layout carbon fiber parts...
It looks like the resin does not fill in the carbon part really well...see photo
Here is my process:
- Mold with gel coat and easylease release agent (I have no problem releasing the part)
- Temperature 23-25 C
- This part (but I get the same with all parts) is 1 carbon (1st layer) and 3 glass
- I use a 1.3:1 in weight for the amount of epoxy vs material
- I use the easycomposite roller to remove air bubbles etc...at each layer. This time, even, to try and see if it would help, I used a heat gun on each layer to get rid of micro-bubbles. But made no difference.
- Then I put a release tissue, a perforated film and a layer of
special
foam to absorb the excess of epoxy.
- Vacuum bagging overnight
But still I get this...which gives me lots of work to give it a proper finish afterwards...
Any idea what I do wrong ?
Thanks !

Oh ! Too much vacuum is something I did not consider ! Thanks for the tip ! I will reduce it and try. Thing is that infusion seems a bit tricky for a newbie like me !

Nah the thing with infusion is that as long as you follow the process correctly and don't cut corners or rush, it will guarantee your part comes out perfectly (provided your mould is perfect of...

For wet bagging your resin should equal the amount of cloth. If your cloth weighs 1000 grams then you should mix an equal amount of epoxy. Too much resin will cause the excess resin to shrink...
