摘要：

实测织物的组织结构参数和纱线的交织规律，建立了玻璃纤维平纹织物几何模型，利用有限元方法对玻璃纤维织物的热传递性能进行数值模拟。与显微镜图像对比表明，织物模型很好地反映了其几何结构特点。数值模拟结果可直观显示在不同时间点织物上的温度分布情况。对织物进行烧蚀试验，将所测织物上的温度随时间变化曲线与数值模拟结果进行比较，结果显示两者在同一时刻温度的平均相对误差在10%以内，模拟结果能直观反映织物组织结构对热量传递的影响。

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
