ARTICLE ANNOTATION

quote
The article is devoted to the study of the structure of structural fabrics and deformation properties of prepregs. The force of deformation of the structural fabric in the composition of the composite material with the load applied to the composite has been increased. The issues of using the arsenal and the main points of analyzing the structure of tissue structures are touched upon. Based on the phenomenological concept of mechanics with the involvement of theories of long-term strength, the process of accumulation of damage to textile threads was studied.The criteria for evaluating the structure of woven structures using the arsenal of knot theory are considered, in particular, a class of single-layer fabrics of arbitrary weave from warp thread and weft of any fibrous composition. Such a structure is represented as consisting of elementary cells, which in an integrated form determine its structural ability. The structural analysis made it possible to assess the degree of nodulation of the threads in the fabric according to a well-known formula. Extensive experimental material on the study of creep and relaxation properties for various textile materials is presented. Linear – viscoelastic ratios and the criterion of long–term strength were used to assess the stress-strain state of threads on a loom. The parameters are calculated from experiments to determine the destruction of threads and damage coefficients at various loads and times. When determining the parameters of the influence function, the three–parametric Rzhanitsyn-Koltunov kernel is used. It is noted that the viscoelastic parameters and elastic modulus of the threads determine the behavior of the warp and weft threads in different areas of the loom.
