Simulation modeling of porous structure of reinforcing chemical threads

The article describes the process of impregnating of reinforcing fibrous fillers made from chemical fibers during the production of fibrous polymeric composites. The impregnation is one of the most important stages of the production of such materials, affecting the operating characteristics of finished products. Strong influence on the quality of impregnation has a porous structure of a reinforcing fiber material. In order to analyze the impregnation process and regulation of the capillary properties of the reinforcing fibrous material, simulation of its porous structure was carried out. The mathematical model and software based on it that performs the simulation of the porous structure of the fiber material was created. Comparison of simulation results with experimental data was conducted, which showed high accuracy of the model.
