Susan, thanks for your thoughts. I've already tested the
preg for proper flow. What I'm looking at right now is
increasing the thickness of the press pads and increasing
the rate of rise. I've been told that this could help.
Thanks, Eddie Rocha
If they are in the prepreg and are present as pressed, then
there is a
mismatch between the prepreg and pressing conditions. Are
you able to do a flow
test on some sheets of prepreg alone to see if the % flow
is as expected? Can
you determine if you are getting the predicted thickness of
the prepreg
layer? Are you able to determine if you are hitting the
correct temp before you
hit the higher pressure during the lamination cycle?
Is the excess around the edges of the panel "frothy" in
appearance?
Just little thoughts that I would use to attack and "fix"
the problem.
Susan
