I just came up with an idea for removing the foam ribs in a composite mold for increased lightness.

Step
1) Layup 1. Carbon fiber(s) layer (vacuum bag).
2) Plastic layer.
3) Foam rib, clay, whatever needed to get the desired shape.
4) Plastic layer.
5) Layup 2. Carbon fiber(s) layer (vacuum bag).
6) Open plastic section, remove rib material.
7) Glue back together for completed part.

This method could also be used for creating two oddly shaped parts that closely fit together.

I'll be using this method to reinforce a body molded seat and for attaching components to that seat.

I'm sure I'm not the first to come up with this idea.

Does anyone have more information on this method or similar?
