Abstract:

Based on the structure parameters of measured fabrics and yarns intersecting pattern, the geometric model of glass fiber plain fabrics was established. The heat transfer performance of fabrics was numerically simulated by using the finite element method. Compared with the microscope image, the fabric model well reflected the geometric characteristics of fabrics. The simulation results of fabrics heat transfer process can visually displayed the temperature distribution at different points. The ablation test was carried out by using alcohol burner. By comparing the variation of temperature to time on tested fabrics with simulation results, the average relative error of temperature at the same time was lower than 10%, and the results also visually displayed the influence of fabric structure to the heat transfer.

Key words: heat transfer, numerical simulation, yarns path, glass fiber fabric
