First, let me answer this. We got square tubes. I believe it comes in a whole array of shapes and sizes. We took the unistrut, machined it down to a size that would nest tightly, but not too tightly, in the FRP. Then, we taped the hole, and screwed it in at a 90 degree angle to the instruct.
This is not frame related in the aspect you are asking about. Team 93, in addition to using the fiber glass (FRP), we also used a large 1/4 in. plate for mounting things, instead of using more pieces of 80/20. We used it to mount gear boxes, our battery, our electronics box, our programming, air compressor, etc. To make this plate strong we had one of our engineers brothers laser cut, then bend out 'ribs', if you will, to make sure it would not flex in any critical part. This part helped the robot meet the weight requirement and still stay robust.
I'm sure myself or Sean Schuff could conjure up some pictures of this plate so you can understand what I'm rambling about.
