I have not made any laminated bamboo bows with interior laminations so do not claim any expertise. I know several bowyers, who are good friends, that sell bows with bamboo laminations in some of their models of bows. These guys are highly respected nationally known bowyers. They have told me that they use bamboo flooring as their primary lamination source. It comes in various sizes, colors and lengths and can be ripped down for interior laminations. Check the internet for sources or your local big name stores. You asked for specific info on laminates so hope this helps.
