- Abstract
Lignocellulosic materials from the stems of annual plants. As part of the research, lignocellulosic materials were produced based on parallel gluing of whole (not crushed into small particles) stems of goldenrod, hemp, miscanthus and willow twigs using polyurethane glue. The stems of goldenrod, hemp and miscanthus were crushed before gluing in order to "open" the tubular structure. For the materials produced, the density, density profile, modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB), thickness swelling (TS) and water absorption (WA) after 2 and 24 hours of soaking in water were tested. The produced materials had a density of 500 kg/m3 . The material made of willow twigs was characterized by the highest strength parameters. Materials made of goldenrod or hemp showed comparable strength parameters, but significantly higher than the strength parameters of the material made of miscanthus. The material made from miscanthus was characterized by the highest resistance to water.
