1.1 本指南适用于使用织物预成型件（如编织物、编织物、缝合预成型件等）作为增强件制造的纺织复合材料的测试。本指南旨在: 1.1.1 确保在测试中适当考虑这些材料的独特特性。 1.1.2 协助用户选择目前可用的最佳ASTM测试方法，用于测量此类材料的常用评估材料特性。 1.2 指出了当前ASTM测试方法不能满足纺织复合材料测试需求的领域。 1.3 本指南并非旨在涵盖所有可能用于纺织复合材料的测试方法。仅包括最常用和最适用的标准。 1.4 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的； 因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不得组合。 1.4.1 在文本中，英寸磅单位显示在括号中。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管要求的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 本指南旨在作为纺织复合材料测试的参考。 4.2 使用本指南可确保在测试中适当考虑这些材料的独特特性。此外，本指南还帮助用户选择目前可用的最佳ASTM测试方法，用于测量通常评估的材料性能。

1.1 This guide is applicable to the testing of textile composites fabricated using fabric preforms, such as weaves, braids, stitched preforms, and so forth, as the reinforcement. The purpose of this guide is to: 1.1.1 Ensure that proper consideration is given to the unique characteristics of these materials in testing. 1.1.2 Assist the user in selecting the best currently available ASTM test method for the measurement of commonly evaluated material properties for this class of materials. 1.2 Areas where current ASTM test methods do not meet the needs for testing of textile composites are indicated. 1.3 It is not the intent of this guide to cover all test methods which could possibly be used for textile composites. Only the most commonly used and most applicable standards are included. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4.1 Within the text the inch-pound units are shown in brackets. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory requirements prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide is intended to serve as a reference for the testing of textile composite materials. 4.2 The use of this guide ensures that proper consideration is given to the unique characteristics of these materials in testing. In addition, this guide also assists the user in selecting the best currently available ASTM test method for measurement of commonly evaluated material properties.
