Sol-gel Wood Preservation

Under changing temperature and humidity conditions, organic material is biodegraded by microorganisms, rot appears, and wood is destroyed, which leads to a loss of operational reliability of wooden structure elements as a whole. To maintain the working condition of wooden structures, extend their life cycle, and ensure operational reliability, it becomes necessary to carry out work to strengthen and repair the surfaces of wooden elements. The article’s authors have developed polymer compositions that can be used to restore the bearing capacity. The first composition was developed based on epoxy resin, and the second was based on dimethacrylic polyester. Conducted tests to determine the compressive strength and shearing along the fibers and the adhesive strength in shear and bending of the wood-composite element. It has been established that the compressive and chipping strengths of impregnated samples are comparable to the strengths of "healthy" wood. The developed composition, based on epoxy resin, showed high adhesive-cohesive properties. It is shown that both materials equally provide the restoration of destructed elements and increase their bearing capacity. Science-based technical solutions for the restoration of local areas of destructed wooden structures can be used in projects to reconstruct, repair, and restore wooden buildings and structures.
