This article presents a mathematical model of calculation the strength characteristics of the composite laminated plates. The dependence allows to estimate the optimal process conditions of laminated plates in static bending. Investigating the structural strength of the new material that is highly anisotropic mechanical properties, proposed in this article a mathematical calculation, allows us to predict what will change the characteristics of strength of anisotropic wood. Obtained relationships can be applied not only in the calculation of the resistance to bending, but in tension, compression, scaling, crumpled on the verge of loads, according to Hooke’s law, to explain the options stress distribution in the samples of different thicknesses (bedding), both the material and in the adhesive layer and veneer. Prospects in this regard are opened with a combination of multi-layered wood with plastics, metals and other materials.
