I have been thinking a lot about different methods to join composite panels in order to eliminate the usual external fiberglass taping. The goal being the elimination of hull fairing. I made many different test panels. It was very interesting to see how they went together. It was also interesting to discover how they failed when subjected to bending loads.
My preliminary conclusion is that the usual way of joining panels together is very good. It is lighter, stiffer, stronger and quicker to make than all the others that I have tried. Of course there is some filling/sanding to do on the hull outside, but I am working on a way to minimize that as much as possible.
