In composites one doesn't cut threads for either bolts or inserts if one is smart but instead molds them with epoxy, etc in place giving good holding and locking in many cases. If a sandwiched material one hollows out the foam/etc core and fill it with epoxy to spead the load, then insert the bolt, insert, etc as needed.
In other plastics drilling a smaller hole then screwing a hot bolt, insert into it gives the needed strength in many cases.
If higher loads than the local material can handle glue on a reinforcement piece with the threads built into it.
As for working loose there are many types of thread lockers out there.
