I have several composite reference handbooks and have listed them here. They all have some good design information on sandwich construction.
Fiber Reinforced Composites - Materials, Manufacturing, & Design; by P.K. Mallick
Principles of Composite Material Mechanics; by Ronald F. Gibson
Design and Manufacture of Composite Structures; by Geoff Eckold
Fundamentals of Composite Manufacturing: Materials, Methods, and Applications; by A. Brent Strong
Composite Materials Handbook; by Mel Schwartz
I found the best information on sandwich construction/design to be in the books by Mallick and Eckold
