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.
