The history of the material began shortly before the Great Patriotic War. The Soviet Union was actively rearming itself; the shortage of light aluminum and magnesium alloys gave rise to the need for a material comparable to them in mechanical properties, but more accessible. The technology of its production was developed by chemist Ya.D. Avrasin and was immediately introduced by the aircraft manufacturer V.P.


At that time, it looked like this:

The veneer was glued into sheets of a large area; They were soaked in bakelite varnish

The resulting layered cake was not much inferior to the strength of steel, while it was much lighter and was not afraid of moisture. Very quickly, bakelite plywood spread from aircraft construction to other industries.

Keruing and Okoume marine plywood is made of exotic tropical species of the same name, characterized by a long service life and the highest mechanical strength. It is it that is most often used in the construction of boats and yachts. However, it is produced exclusively abroad, so the price of the material (from 1200 rubles per square meter with a thickness of 3 mm) makes it quite an overhead purchase; The domestic version is made from birch veneer and costs about half the price.
