New 'foam' core material?

Like whether you have enough buns for your dogs? Or if your SPF is high enough

All very interesting.

All not very much informed....

Al burns from a lighter!

Steel burns from a candle!

Who is idiotic enough to compare a plate of either material with a mesh, foam or "wool" ?

AL foam can be ignited whith a lighter when carbon content and O² is present.

Steel wool can be as easy ignited when the same (high carbon, high O²) concentration is present.

Can you imagine a engine room with a throughput of just 30m³ of air per minute?

The "new" Al foam in question here, has nothing to do with boat or shipbuilding, thats it.
As nobody would assume that any sort of other metal foam or "wool" would have. They burn like hell.

Now we wait for someone to try it on a sailboat.

Aluminium core in jump ski's (water)has worked great for 30 years.
Aircraft/F1/18foot skiffs( when in their expensive mode)/water skis,thats the order for common usage of new composites as far as I can tell.
As for cheap composites that would be production recreational boat building where anyone can do anything they like.
( like use balsa with polyester non bagged layup)
