Hi I am doing Vacuum Bagging and in the final part there are gaps/voids where the warp and wept intersect. Here is an image of it. Can anyone help please?

If you are not using a perforated release film between peel-ply and breather material, a lot of the resin will end up in the breather material, especially with a poor vacuum.

If your Vac-bag is completely sealed, it should hold vacuum for at least the time it takes for the initial cure of the epoxy .. even when turning off the pump -- also do ensure that you clamp the vac-hose form your bag to the pump.. In my experience a lot of laboratory vac-pumps have no stop valve .. so air will leak back through the pump ..
