Standard Test Method for Transverse Compressive Properties of Hoop Wound Polymer Matrix Composite Cylinders 环形缠绕聚合物基复合材料圆筒横向压缩性能的标准试验方法
发布日期: 2022-05-01
1.1 本试验方法测定了由高模量连续纤维增强的缠绕聚合物基复合材料的横向压缩性能。它描述了轴向压缩环绕(90°)圆柱体的测试,以确定横向压缩性能。 1.2 自1993年以来,该测试方法的技术内容一直稳定,没有利益相关者的重大反对意见。由于本试验方法的维护技术支持有限,自该日期起的变更仅限于与其他ASTM D30委员会标准保持一致所需的项目,包括编辑性变更和纳入关于试样预处理和环境试验的更新指南。 因此,试验方法不应被视为包括自1993年以来方法和实践的任何重大变化。测试方法的未来维护将仅响应特定请求,并仅在技术支持允许的情况下执行。 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。每个系统中规定的值不一定是精确的等价物;因此,为确保符合本标准,每个系统应独立使用,且两个系统的值不得组合。 1.3.1 在文本中,英寸-磅单位显示在括号中。 1.4 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、健康和环境实践,并确定监管限制的适用性。 1.5 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法旨在产生横向压缩性能数据,用于材料规范、研发、质量保证以及结构设计和分析。因此,应报告影响横向压缩响应的因素:材料、材料制备方法、试样制备、试样调节、测试环境、试样对齐和夹持、测试速度、空隙率和纤维体积分数。 可从本试验方法中获得的试验方向特性为: 5.1.1 横向抗压强度σ 22 坎特伯雷大学 , 5.1.2 破坏时的横向压缩应变,ε 22 坎特伯雷大学 , 5.1.3 横向压缩弹性模量, E 22 和 5.1.4 泊松比,γ 21 .
1.1 This test method determines the transverse compressive properties of wound polymer matrix composites reinforced by high-modulus continuous fibers. It describes testing of hoop wound (90°) cylinders in axial compression for determination of transverse compressive properties. 1.2 The technical content of this test method has been stable since 1993 without significant objection from its stakeholders. As there is limited technical support for the maintenance of this test method, changes since that date have been limited to items required to retain consistency with other ASTM D30 Committee standards, including editorial changes and incorporation of updated guidance on specimen preconditioning and environmental testing. The test method, therefore, should not be considered to include any significant changes in approach and practice since 1993. Future maintenance of the test method will only be in response to specific requests and performed only as technical support allows. 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 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. 1.5 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 transverse compressive property data for material specifications, research and development, quality assurance, and structural design and analysis. Factors that influence the transverse compressive response and should therefore be reported are: material, method of material preparation, specimen preparation, specimen conditioning, environment of testing, specimen alignment and gripping, speed of testing, void content, and fiber volume fraction. Properties in the test direction that may be obtained from this test method are: 5.1.1 Transverse compressive strength, σ 22 uc , 5.1.2 Transverse compressive strain at failure, ε 22 uc , 5.1.3 Transverse compressive modulus of elasticity, E 22 , and 5.1.4 Poisson's ratio, γ 21 .
