The results of theoretical and experimental studies to identify the influence of physical factors on the fracture toughness improved monolithic structure of the composite material.

Rail transport, including forestry one, with extremely slow construction of roads in Russia in the coming decades will be the primary means of transportation.
One of the main, but also the most vulnerable, from a position of operational life, elements of the superstructure of railroad tracks is a sleeper. Statistics show that in the world of railway construction the most common material for sleepers is wood. Sleepers on this basis are up to 80% of the total number and have normative service life in the impregnation with antiseptics of 14 ... 25 years, which is reduced due to the intensification of traffic and increasing loads and speeds up to 8 ... 10 years. At the same time, we know that to replace each year sleepers and on the development of the rail network it is necessary to cut down up to 12 million m3 of forest which are the lungs of the planet, and these are the trees at the age of 80 ... 100 years.
