description: Topic of the final qualification work: "Modeling the impregnation of reinforcing fabric and numerical prediction of permeability, taking into account fiber shear". This work is devoted to the numerical simulation of the process of infusion (impregnation) of a woven composite material with resin in the Ansys Fluent software package. The main purpose of the work is to simulate the impregnation of a reinforcing fabric and numerical prediction of permeability, taking into account the shear of fabric fibers. For this, the following tasks were solved: 1. Development of a CAD model created in the Solid Works software package and its import into Ansys Fluent. 2. Setting up model elements and performing calculations. 3. Analysis of the obtained results and verification of the model using experimental data. 4. Writing a script in the Python programming language to automate calculations and simplify model debugging. The work was carried out on the basis of the world-class scientific center "Advanced Digital Technologies" of St. Petersburg Polytechnic University, where the author of the work was provided with the necessary software products and computing power. At the first stage of work in the LS-Dyna and Solid Works software packages, a detailed model and simulation of the drapery of a fabric sample was created. At the second stage, the permeability of the fabric sample obtained during draping was calculated in the Ansys Fluent software package, and the calculation results were verified using experimental data. To automate calculations and easily debug the model using the internal libraries LS-Dyna and Ansys-Fluent, a script was developed in the Python programming language. It is shown that the created numerical model of the gauge is capable of satisfactorily predicting various modes of deformation and stretching of the reinforcing fabric, and modeling its permeability during impregnation (infusion), observed during experiments.
