The way I would do it is make the part this way:Lay your lay-up in the mould and infuse (no honeycomb)
Let it cure and remove vac-bag materials and peelply
Add resin on that layer and put your honeycomb on it
Add some vacuum to firmly bond the honeycomb on that first layer
Wet lay toplayer on a serpearate sheet and put it on top of honeycomb and vacuumbag again
