The use of composite materials in engineering practice and in particular nonmetallic composite materials in the preparation of elastic couplings (clutches) requires modeling of their mechanical behavior. The production of elastic couplings with a elastic element having reinforced polymer materials require studying the behavior of those materials for loads which are typical for their operation. In many modern structures of elastic clutches are used multilayer reinforced composites. This kind of materials are composed of separate layers with different orientation of reinforcing fibers. Several authors have studied the behavior of this type of laminated materials (Yongming L. 2005, Zhang Y.X., 2009). Factors,which determine the stress and deformation state of this type of elastic elements are: — structure and mechanical characteristics — matrix and reinforced material — connection between matrix and reinforced material — orientation of reinforcement. The aim of this paper is to investigate stress and strain state of elastic element of coupling, creating a model for determination of the state of threelayers nonmetallic material for manufacturing of nonmetallic elastic elements.
