Mechanical Properties of Polymer Composition Based on Dimethacrylic Polyester with Nanostructured Filler for Wood Modification

Polymer materials are used in a variety of sectors of the national economy, including in construction. Due to the development of science and technology, higher and higher requirements are being imposed on them, which conventional polymers no longer satisfy. Significantly improve the performance properties of polymers allows the creation of polymer composite materials based on them. One of the promising areas of research in the field of composite materials is the creation of polymer composites based on carbon nanotubes (CNTs). The effectiveness of the use of wooden structures can be increased by modifying wood. Modification is proposed to be carried out using a polymer composition based on dimethacrylic polyester with a nanostructured filler. The solution of this problem will allow, with an increase in strength and rigidity, to reduce the material consumption and installation weight of structures, to reduce the influence of anisotropy of properties and defects of wood on the bearing capacity. In order to establish the mechanical properties of wood, experimental tests were carried out with a polymer composition without filler and with a nanostructured filler. The increase in strength properties with the introduction of filler was 27.7% in compression tests and 23.49% in tensile tests. Studies have proved the promising possibility of using a polymer composition for wood modification.
