Abstract (English):
The article examines the content of the technology for obtaining a new material, strengthened by modifying wood from low-value deciduous species of the Drevstal trademark. The technology includes stages of exposure to ultrasound during plasticization, three-sided compression, exposure to liquid nitrogen and a short-term pulsed magnetic field. Products made from this material have a competitive advantage over similar products made from metals and plastics.

Keywords:
modified wood, pressing, ultrasound, pulsed magnetic field, liquid nitrogen, density, hardness
