【 摘 要 】

The paper discloses the method for estimating the deformation of fibroreticulate materials under the conditions of spatial multiaxial cyclic tension. The relevance of the method application for estimating the reliability performance of materials used for upholstering and finishing the interior of aircraft cabins has been justified. The equations of the elastic state of flexible fibroreticulate materials are obtained under the spatial tension in stresses and deformations. The geometric parameters of elastic deformations in the material during in the material in the design, processing treatment (molding process) and operation (shape stability) of the products. The advantage of the developed method of spatial cyclic tension of flexible fibroreticulate materials is the ability to model test conditions that simulate operating conditions. This capability of the test method allows to examine the dynamics of changes in the markers of the molding properties and shape stability of materials and to predict their behavior during operation.
