1.1 该测试方法确定了纤维增强聚合物基复合材料的全厚度“平面”拉伸强度和弹性模量。使用粘结的厚金属端片垂直于复合层压板的平面施加拉力。复合材料形式限于连续纤维（单向增强或二维织物）或不连续纤维（无纺或短切）增强复合材料。 1.2 使用该试验方法的全厚度强度结果通常无法与试验方法进行比较 D6415型 因为这种方法使相对较大体积的材料经受几乎均匀的应力场，而试验方法 D6415型 使小体积的材料经受不均匀的应力场。 1.3 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定完全相等；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得合并。 1.3.1 在文本中，英寸- 磅单位显示在括号中。 1.4 本标准可能涉及危险材料、操作和设备。 1.5 本标准并不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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 该测试方法旨在为结构设计和分析、质量保证以及研发提供全厚度失效数据。影响整个厚度抗拉强度的因素，因此应报告如下:材料和织物加固、材料和织材料制备方法、加工和试样制造方法、试样堆叠顺序、试样调节、试验环境、试样对齐、试验速度、温度时间、空隙含量、，以及体积钢筋含量。

1.1 This test method determines the through-thickness “flatwise” tensile strength and elastic modulus of fiber reinforced polymer matrix composite materials. A tensile force is applied normal to the plane of the composite laminate using adhesively bonded thick metal end-tabs. The composite material forms are limited to continuous fiber (unidirectional reinforcement or two-dimensional fabric) or discontinuous fiber (nonwoven or chopped) reinforced composites. 1.2 The through-thickness strength results using this test method will in general not be comparable to Test Method D6415 since this method subjects a relatively large volume of material to an almost uniform stress field while Test Method D6415 subjects a small volume of material to a non-uniform stress field. 1.3 Units— 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. 1.3.1 Within the text, the inch-pound units are shown in brackets. 1.4 This standard may involve hazardous materials, operations, and equipment. 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 limitations 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 ====== 5.1 This test method is designed to produce through-thickness failure data for structural design and analysis, quality assurance, and research and development. Factors that influence the through-thickness tensile strength, and should therefore be reported, include the following: material and fabric reinforcement, methods of material and fabric preparation, methods of processing and specimen fabrication, specimen stacking sequence, specimen conditioning, environment of testing, specimen alignment, speed of testing, time at temperature, void content, and volume reinforcement content.
