Physical and Mechanical Properties of Coniferous Wood After Exposure to Fire

The technical qualities of wood are characterized by a significant number of its physical and mechanical properties. The technical qualities of wood are greatly affected by fire. Since there is currently an acute shortage of hardwoods, the issue of maximizing the full use of natural wood resources through wider use where possible is particularly relevant. Thus, one of the main issues of forest research is the question of the technical quality of fire-damaged wood and the possibility of using it as a structural material. In this project, studies were carried out on the structure of raw wood - pine, exposed to fire. At the investigation stage, it can be noted that, based on visual analysis of the samples, no damage caused by insects and fungi was noted within five to seven months after the fire. According to the results of tests of samples for compression along the fibers, tension along the fibers and static bending, with a sufficiently small damage to the tree by fire, it can be recommended that it be partially used as a structural material.
