1.1 本试验方法描述了用于加固由金属、木材、砌体和钢筋混凝土等材料制成的结构的扁平纤维增强聚合物（FRP）复合材料的样品制备、拉伸试验和结果计算的要求。该方法可用于测定现场制造或工厂制造的湿铺和预浸渍FRP复合材料的拉伸性能。FRP复合材料可以是单向（0度）或交叉层（0/90型）钢筋。对于交叉层压板，可以使用0度或90度的多层单向纤维，或一层或多层0/90缝合或编织织物来实现结构。复合材料形式仅限于连续纤维或不连续纤维增强复合材料，其中层压板相对于测试方向平衡对称。 该方法仅涵盖FRP复合材料拉伸性能的测定。用于将FRP材料附着到基材上的其他组件，如底漆、腻子和外粘结加固系统中的粘合剂，不包括在本文件详述的样品制备和测试范围内。本试验方法是指试验方法 D3039/D3039M 进行测试。 1.2 以国际单位制或英寸-磅单位表示的数值应视为标准值。在文本中，英寸-磅单位显示在括号中。每个系统中规定的值不是精确的等价物；因此，每个系统必须相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 本试验方法可用于获得用于加固其他结构材料（如金属、木材和钢筋混凝土）的FRP材料的抗拉能力和极限拉伸应变。主要测试变量可能是FRP成分和制造方法或FRP层压板的尺寸或类型。获得的拉伸性能可用于材料规范、质量控制和保证、结构设计和分析以及研发。 5.2 该试验方法侧重于FRP材料本身，与夹持方法无关。因此，忽略与任一夹点处的失效或拉拔相关的最大力和应变数据。测力能力和最大应变测量仅基于在量规部分失效的试样。

1.1 This test method describes the requirements for sample preparation, tensile testing, and results calculation of flat fiber reinforced polymer (FRP) composite materials used for the strengthening of structures made of materials such as metals, timber, masonry, and reinforced concrete. The method may be used to determine the tensile properties of wet lay-up and pre-impregnated FRP composites fabricated on site or manufactured in a factory setting. The FRP composite may be of either unidirectional (0-degrees) or cross-ply (0/90 type) reinforcement. For cross-ply laminates, the construction may be achieved using multiple-layers of unidirectional fibers at either 0 or 90 degrees, or one or more layers of stitched or woven 0/90 fabrics. The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. The method only covers the determination of the tensile properties of the FRP composite material. Other components used to attach the FRP material to the substrate, such as the primer, putty, and adhesive in externally bonded strengthening systems, are excluded from the sample preparation and testing detailed in this document. This test method refers to Test Method D3039/D3039M for conduct of the tests. 1.2 The values stated in either SI units or inch-pound units are to be regarded as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 This test method can be used to obtain the tensile force capacity and ultimate tensile strain of FRP material used for the strengthening of other structural materials such as, metals, timber, and reinforced concrete. The principal test variables could be the FRP constituents and fabrication method or the size or type of FRP laminate. The obtained tensile properties can be used for material specifications, quality control and assurance, structural design and analysis, and research and development. 5.2 This test method focuses on the FRP material itself, irrespective of the gripping method. Therefore, maximum force and strain data associated with failure or pullout at either grip are disregarded. The force capacity and maximum strain measurements are based solely on test specimens that fail in the gauge section.
