As a suggestion, you might want to look at "Advanced Composite Techniques" by Zeke Smith (available on Amazon and other places). Also the Glassair site has some interesting info.
Back in the beginning when I thought I had money, I looked into the Glassair III RG (I'd buy one if I could afford it) and was sent a package with just epoxy reinforced glass (I'm familiar, I used to build circuit boards), foam, and an epoxy/glass fabric/foam sandwich... the last was "bullet proof", the others not so much. The stress matrix of the sandwich is significantly higher than the individual components (i.e., the whole is greater...). So the foam does contribute to the overall strength of the structure. The reference explains the technical elements of the physics of the composite structure that even quality engineers / operations guys like me can understand. I think I spent about $15 for the book - well worth the investment if you want to earn the right to sing the sanding song. As usual, JMHO, and your results may vary. Mark W.
