I don't think homebuilders would find it hard to make strong edge bonds when joining flat composite panels. It's a good spot to introduce some internal reinforcement, too. But, if desired, another approach is to make the corners using the "Foldaplane' method used by the Vision. Vacuum bag the foam core and external skin against a flat smooth surface. When cured, cut kerfs in the foam to allow it to be folded at the edges where desired, drop it into exterior bucks of the right shape, then install the bulkheads and interior skin to lock everything in place. Yes, the cut lines still require exterior glassing, but the vast majority of the exterior skin is smooth and almost ready for paint.While I admire the look of all the composite tadpole like designs these are not very accessible for the homebuilder on a budget. The faceted flat panel composite build up is a little more achievable but there are lots of corners dependent on good bonds to achieve strength.
I'm wondering at this point if its easier, simpler and less expensive to build the fuselage pod with ply skins on the inside of the framework whch carries the load paths, infill the sides of the structure with foam and add some compressive areas in the nose and under the seat. You could then carve to a pleasing shape and wrap with kevlar/carbon for a strong pod structure ala 21st Century KR1/2 and vari eze. Just thinking out loud as to how I could do this in my garage.
