@mijostyn Your description of a Densified Wood and in your case the reference to Panzerholz is quite limited in description and does not demonstrate where it separates as a Production Method to a Typical Reference to a Plywood.
The Process used to produce a Phenolic Resin Densified Wood is using extreme compression multiple layer of a Veneer. The Veneers are to receive a specified volume @ g/m2 of Phenolic Resin between each layer of Veneer in the Ply Assembly.
This is then compressed as an assembly to reduce the original thickness by 50%, a 1.4 mm Veneer will compress to approx' 0.7mm.
The entire assembly is then Vacuum Treated (removes all air pockets from imperfections and the Woods Cell Structure, which will be filled with the flow of the Phenolic Resin).
There is also a process to administer a Heat Treatment.
Densified Woods are now with a Patent in place for more than 100 Years and the Production Technology and extended use of application for the product due to this has been an evolving R&D.
The Dynawood Brand for Densified Wood is one that has a selection of Colours as the Option, but this suits a particular industry, such as Knife Handles.
The statement made about the use of Aluminium and P'holz for the same role and having same impact is pure conjecture, if one took the time to review the Measurements as a result of Damping and Frequency response they could not so flippantly make such a statement.
There are obvious differences between the effect the two materials will have to be anticipated as occurring, there is data to explain differences when discovered.

Another case in relation to your remarks of the 'Old Guard' getting it quite wrong in relation to what is required for modern military manoeuvres.
