Rib Tape

For the 2013 Team Trials I did a run of planes with Kevlar tissue on all the ribs hoping to help keep the plane together after a collision. The tissue is non continuous fibers. The performance was improved but not as much as I would have liked. The ribs stayed together something like 40-60% better but not 100%. One unforeseen benefit was that when making repairs the fibers overlapped the break most of the time so when I CAed the wood the Kevlar was again acting as a reinforcement.

The Kevlar is expensive and laminating the tissue is a pain on a large scale. So what about tape? More than a few planes available from the EU are coming with clear tape on the ribs so someone other than me has had this same thought. Looks cool too!
