Abstract
The paper presents the results of experimental studies to determine the mechanical characteristics (Poisson's ratio, modulus of elasticity, tensile strength) of carbon-based composite materials with different compositions according to the number of layers and the direction of the fibers in it. A mathematical model is proposed, which allows, in the first approximation, to determine the main mechanical characteristics of the composite material and takes into account its structure (the maximum number of layers of composite material, which was considered in this work - 7). The parameters of the model were determined by the conducted regression analysis. The results of analytical calculation according to the proposed model are compared with the experimentally obtained values of mechanical characteristics. It is shown that the maximum error does not exceed 12%.
