Re: Material: Super wood
In Response To: Material: Super wood ()

Have any of you heard anything about super wood? If this becomes commercially available I wonder if the properties would be beneficial to kayak building. They mention it makes balsa usable for furniture. The process makes the wood thinner and denser.

From that article:

The wood is reportedly just as strong as steel, but six times lighter in weight and five times thinner than the original piece.

The SpecificGravity of steel is 7 or 8 (?) so this 'superwood' would be quite dense/heavy, I think.

It's hard to tell if the 'stronger' claim is comparing equal thickness or equal weight samples.

For wood-core composite (aka strip building) construction, I don't think a thinner core that's heavier has a big advantage. Perhaps for spots where the wood part is more 'structural', it might have a use?

Actually, when you look at the properties of 'ordinary' wood compared to other materials, it's quite remarkable already.

For some interesting reading, check out 'Chapter 3: Wood as a Structural Material' in this book:
