资源简介：
The subject of the invention is a method of the thermomechanical densification of poplar plywood consisting of heating poplar plywood characterised by the fact that plywood of a moisture of 5-15% is subjected to is subjected to interval compression between the press plates， where the poplar plywood is heated to a temperature between 70° -105°C， and then compressed in 2-3 cycles under pressure of 5-20MPa， reducing the thickness of the plywood to 25-50% of its original thickness. Furthermore， the plywood obtained by the method according to the invention is characterized by relative deformations of 50%-75%
