报告题目：Research of Wood Shape Memory Effect at Low Temperatures

摘要：
On September 21, 2019, Russia ratified the Paris Agreement. Russia has set a goal to reduce greenhouse gas emissions to the level of 70-75% relatively to the indicators of 1990 including taking into account the absorption capacity of forests. Russia has more than a fifth of the world's forests, holds a leading position in the world in total forest area and the second one in timber stock and has a great potential for carbon sinks in forests and wood products for climate change mitigation. Requirements of multifunctionality, i.e. combination in the material of high physical, mechanical and chemical properties are imposed to modern materials. Wood is the natural multifunctional material with high mechanical properties at the low density, possesses the shape memory effect. Extreme impacts on wood can lead to creation of essentially new structural states. The results of the research of the shape memory effect of wood at low temperatures are presented. The deformative conversions, quantities of wood shape memory effect (Rr and Rf) for specimens of sliced and rotary-cut veneer of pine, beech and birch in temperature intervals from +100 to -71 °C were experimentally investigated. Results of research can be used for the development of new multifunctional biodegradable wood-based materials capable of operating under variable extremal temperature and humidity conditions.
