epoxy a strap of carbon fiber tape (say 1" wide) in front and behind your new bulkhead. You can also run cf fore and / or aft to the next structural bulkhead to distribute the loads. It adds a huge amount of strength to the fiberglass, and widens the load footprint so the stresses are disappated over a wider area of the fuselage............
Good points, Wayne. In the orig, there is a rib encircling the fuse at the area where the bulkhead attached. There are also longerons attached to the skin. These are the aluminum equivalents of the same reinforcement you suggest.
In the larger sense, what is important is to feed the loads into the structure without distorting the structure. The semi-bulkhead accepts those loads and the loop of CF you propose will certainly help. Even eggshells are pretty strong until they begin to distort...then it's Omelet City!
