Carl and Gareth,

I found your post about impregnated aluminum very interesting this morning, not for the boating community, but for the transportation community. Specifically, using the sandwiched aluminum and even more importantly, the composite aluminum as bridge components. Since I have not been in the bridge community for a few years now, I forwarded on your posts to a US bridge expert in high-performance materials for his consideration. He should know whether we have already tried it, are considering trying it, or should consider trying it. Thank you for sharing the information. You may be revolutionizing bridge design and construction with you posts here on Catsailor.
