I also like this video about carbon fibre skinning which reminded me of another lecture at uni.

I had never looked into it, titanium is pretty soft…wow. Cool, thanks Barry. I am going to close that tab now, No titanium for me.

That may be dependent on grade. Porsche has offered optional titanium connecting rods on street cars with factory warranties and titanium valves are pretty common in performance engines.
