Aviation grade plywood

Aircraft plywood meets MIL-P-6070B

The mill specification requires that the plywood be tested for general condition of boards, deviations of thickness, moisture content, tensile strength of wood, gluing strength, bending test, torsion test, immersion test and boiling test

Aircraft plywood is produced by using glues of the thermosetting, synthetic resin type

The quality requirements for plywood to be used in aircraft are much more exacting than for industrial plywood in general

High-strength plywood, also known as aircraft plywood, is made from mahogany, spruce and/or birch using adhesives with an increased resistance to heat and humidity

It was used in the construction of air assault gliders during World War II and also several fighter aircraft, most notably the multi-role British Mosquito
