Very interesting stuff… Shows how susceptible composites are to quality products and methods.
Might want to take time to read this material study.
Destructive testing comes in handy too 
Make a sample joint/bond with two laminates as in your product design, then see what it takes to destroy it… or not destroy the bond. Destruction is more fun!
Destructive test and inspection is cool!!!
Thanks for the great post :)!
Even after many years, thanks for the post
