I would like to put some threaded inserts into my finished carbon fibre piece, bonded like you guys did with the fittings on the car bonnet instructional video project. I have see Warren mention 'off the shelf' inserts that have the perforated or scored load plate on them for better bonding but can't find a source of these off the shelf inserts. 

How much load will be on those M5 inserts?

You may well be able to get away with drilling and tapping some small pieces of Aluminium/stainless-steel "sheet metal"  like 2- 3 mm in thickness ..


I have made a few like that.. on some of them i did not even drill and tap them before bonding them in .. they were placed in the "stack" at roughly the right places.  Then the holes were marked and drilled and tapped after the parts had cured, using the other part as a precise "template" for the holes ..
