标准范围

本文件规定了自动测定织物变形性的方法，包括连续纤维增强织物。该方法不适用于树脂浸渍织物。该方法适用于织物，例如用于增强复合材料的机织物或针织物、非织造布、非卷曲织物、由玻璃粗纱或无捻碳纤维长丝制成的织物。将该方法应用于多轴向非卷曲织物时，纤维方向和间隙的评估仅包括最上层。该方法可用于粉末粘合剂处理的织物。

This document specifies a method for the automatic determination of the deformability of textile fabrics, including continuous-fibre reinforcement textiles. This method is not applicable to resin impregnated fabrics.The method is suitable for use with fabrics such as woven or knitted fabrics, nonwovens, non-crimp fabrics, fabrics made of glass rovings or untwisted carbon filament yarns intended for reinforced composite materials. When applying the method to multi-axial non-crimp fabrics, the evaluation of the fibre orientation and gaps only incorporates the uppermost layer.The method can be used for fabrics treated with powder binder.
