No, density is doubled, but strength is increased 11×, according to the paper. Sandwich panels with strong, stiff face sheets will always beat relatively homogeneous material like natural wood for the kinds of applications you are talking about.

Oh interesting, then it laminating thin sheets of this should be far lighter for the same strength, I didn't expect the strength increase to be anywhere near 2x much less 11x.
