Heavy-duty wood:

Heavy-duty wood is stronger than the usual 12 times. This wood can replace steel and some titanium alloys. However, it is lighter than metals and alloys and easier to process.

Heavy-duty wood obtained from ordinary wood of any breeds of a tree by its processing. First it is boiled in a solution of sodium hydroxide and sodium sulfite to partially extract from the lignin and hemicellulose. Then, the treated wood is subjected to hot pressing between metal platesheated to 100°C at a pressure of 5 MPa. In the end it is three times denser, 10 times tougher and up to 12 times stronger.

Obtained by processing heavy-duty wood can be used to create light and strong structures, including elements of vehicles, aircraft, buildings and structures.
