Elements of bases of mechanics of wood-polymer composites

. Disclosed is a solution of a particular case of a problem of polycomponent motion within a poly speed model, which is reduced to setting conditions of joint motion of components and determining intercomponent thermal-force interaction. The study of construction of the basis of mechanics of wood-polymer composites from phenomenological positions of mechanics of heterogeneous media is presented by construction of equations of laws of mass and momentum preservation for two component media and their closure by a viscous-elastic-plastic rheological model of the composite material for development of the basis of mechanics of wood-polymer composites from phenomenological positions of mechanics of heterogeneous media, Contributing to improvement of production of structured composite for FDM - printing technologies due to production of composites on the basis of thermopolymers with filling of them with ground wood. Raw materials can be wastes of logging and wood processing industries, the product is a composite with high filling of wood with a wide field of application in different sectors of national economy and industry. The equations are closed by a viscous-elastic-plastic rheological model of the composite material and by matching the equations of inseparability and the displacement strain vector.
