I am working with a group of US veterans teaching them composite prepreg layup techniques and am having problems with what are either air bubbles or resin bubbles. Here is a pic. under a 10x300x microscope:
Any suggestions as to what is wrong?

     is this after cure? If so what was the process involved, autoclave OOA and was there sufficient vacuum of the bag during cure?
