1.1 本指南为纤维增强复合材料以及纤维、填料和芯材料、基体、预制件、预浸料、工艺和这些复合材料中使用的零件建立了必要和理想的识别元素。本指南旨在准备测试报告、数据库和材料文档。 1.2 这些指南专门针对纤维增强聚合物基复合材料。也包括也含有颗粒或沉淀颗粒的复合材料，前提是它们可以充分描述为基质中的填料。 1.3 本指南涵盖的材料包括连续和不连续的纤维，以及用作复合材料增强材料的各种几何形状的填料，以及用于夹层复合材料、热固性和热塑性基体、纤维预制件、预浸料产品形式、制造工艺和通用零件形式的芯材。 芯可以是泡沫、蜂窝或天然材料，如轻木。这些材料与散装材料的区别在于其特殊几何形状对其性能的重要性。这种差异反映在使用几何学和化学作为分类的主要基础上。此外，还定义了被认为是可取的但并非必要的其他数据元素。目的是对不同来源的数据进行有意义的比较。 1.4 本指南中的数据元素与测试数据、在测试实验室获得的数据以及实验室笔记本中历史记录的数据相关。房地产数据，即经过分析和审查的数据，可能只需要这些数据元素的一个子集。 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。 1.6 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《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====== 4.1 本指南提供了用于识别纤维增强复合材料的推荐数据元素，以及对唯一描述纤维、填料或芯材至关重要的信息。 4.2 本指南旨在提供足够的详细信息，使可能影响试验结果或材料特性值的材料参数的值已知。 4.3 本指南仅用于材料识别和说明。它不包括机械测试数据或其他特定类型测试数据的推荐数据元素。 材料规范或其他测试标准中引用的单独格式涵盖了这些项目。 4.4 复合材料是指在宏观尺度上组合的两种或两种以上材料。复合材料和其他材料类别之间存在灰色区域。聚合物基复合材料和塑料之间灰色区域的两个例子是增韧聚苯乙烯和液晶聚合物。 附录X1 包含一个表格，其中提供了区分增强聚合物和聚合物基复合材料的指南。 4.5 复合材料由基体相和一个或多个离散增强体组成。增强可以广义地解释为包括任何宏观第二材料，包括纤维、颗粒、沉淀颗粒或母体材料的结构域。本指南中涵盖的增强材料包括纤维和可充分描述为基质内填料的此类颗粒和沉淀颗粒。 增强材料可以是聚合物、金属、陶瓷或其他材料。本指南通过核心材料的识别涵盖夹层结构。这些指南适用于识别厚度恒定的简单形状的复合材料；例如，板或管。对于复杂结构，可能需要与特定应用相关的其他信息。 4.6 复合材料的分类很复杂，因为复合材料是由不同数量和结构的不同材料组合而成的；这导致了无限多的可能性。有效的识别方案必须能够在不使系统负担过重的情况下进行可能的组合，其细节仅与有限数量的材料系统有关。本指南提供了基本数据元素和被认为可取但不重要的数据元素。如果需要对不同来源的房地产数据进行有意义的比较，则认为数据元素至关重要。 4.7 复合材料组成材料的识别包括在识别复合材料所需的水平上。 4.8 如果指南定义的所有基本信息都存在，则比较不同数据库中的房地产数据将最有意义。如果省略了基本信息，仍然可以进行比较，但比较的有用性可能会大大降低。 4.9 用于识别复合材料， 表1 （A部分）和 表2和 3. 应使用。 （A） 包括非六边形开孔形状，如Flexcore®等。Flexcore®是Hexcel，股份有限公司.的注册商标，已被证明符合此目的。 4.10 用于识别纤维、填料和芯， 表1 （B部分）， 表4- 10 和 表11- 14 应使用。 （A） 字段编号仅供参考。 （B） 应为每个相关尺寸提供尺寸参数和值。 如果给定值，则类型是基本信息。 （C） 对于分布宽度相关的每个维度。如果给定了参数值，则参数是必不可少的。 4.11 用于识别矩阵， 表1 （C）及 表15- 17 应使用。 （A） CMH-17第2卷第1.6.1节和术语 D1600 . 4.12 用于识别预制件， 表1 （D部分）和 表18- 20 应使用。 4.13 用于识别预浸料， 表1 （E部分）， 表5 和 表21和 22 应使用。 4.14 用于识别过程， 表1 （第F部分）， 表16 和 表23- 26 应使用。 4.15 用于识别复合零件， 表1 （G部分）和 表27 应使用。

1.1 This guide establishes essential and desirable identification elements for fiber-reinforced composite materials and for fibers, fillers, and core materials, matrices, preforms, prepregs, processes, and parts used in these composite materials. This guide is intended for preparing test reports, databases, and material documents. 1.2 These guidelines are specific to fiber-reinforced polymer-matrix composite materials. Composite materials, which also contain particulates or precipitated particles, are also included, provided they can be described adequately as a filler in the matrix. 1.3 The materials covered by this guide include fibers, both continuous and discontinuous, and fillers of various geometries which are used as reinforcements in composite materials, as well as core materials used in sandwich composites, matrices both thermoset and thermoplastic, fiber preforms, prepreg product forms, manufacturing processes, and generic part forms. Cores may be foam, honeycomb, or naturally occurring materials such as balsa wood. These materials are distinguished from bulk materials by the importance of their specialized geometric forms to their properties. This difference is reflected in the use of geometry, along with chemistry, as a primary basis for classification. Additional data elements that are considered desirable, but not essential, are also defined. The purpose is to allow the meaningful comparison of data from different sources. 1.4 Data elements in this guide are relevant to test data, data as obtained in the test laboratory and historically recorded in laboratory notebooks. Property data, data that have been analyzed and reviewed, may only need a subset of these data elements. 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 ====== 4.1 This guide provides the recommended data elements for the identification of fiber-reinforced composite materials and the information which is considered essential to uniquely describe a fiber, filler, or core material. 4.2 The intent of this guide is to provide sufficient detail that values are known for the material parameters that may influence test results or material property values. 4.3 This guide is for material identification and description only. It does not include the recommended data elements for mechanical test data or other specific types of test data. Such items are covered by separate formats to be referenced in material specifications or other test standards. 4.4 Composite materials are defined as two or more materials that are combined on a macroscale. There is a gray area between composites and other material classes. Two examples of this gray area between polymer matrix composites and plastics are toughened polystyrene and liquid crystal polymer. Appendix X1 contains a table, which provides guidelines for distinguishing between reinforced polymers and polymer matrix composites. 4.5 Composite materials consist of a matrix phase and one or more discrete reinforcements. Reinforcements may be interpreted broadly to include any macroscale second material, including fibers, particulates, precipitated particles, or structured domains of the parent material. The reinforcements covered in this guide include fibers and such particulates and precipitated particles that can be described adequately as filler within the matrix. The reinforcements may be polymers, metals, ceramics, or other materials. Sandwich constructions are covered by this guide via identification of the core material. These guidelines are suitable for the identification of composites in simple shapes of constant thickness; for example, plates or tubes. For complex structures, additional information relevant to a specific application may be required. 4.6 Classification of composite materials is complicated by the fact that composites are formed by combining different materials in varying amounts and configurations; this results in an infinite number of possibilities. An effective identification scheme must be capable of possible combinations without overburdening the system with details relevant only to a limited number of material systems. This guide provides both essential data elements and data elements that are considered desirable but not essential. Data elements are considered essential if they are required to make a meaningful comparison of property data from different sources. 4.7 Identification of constituent materials of the composites is included to the level considered necessary for identification of the composite. 4.8 Comparison of property data from different databases will be most meaningful if all the essential information defined by the guide is present. Comparison may still be possible if essential information is omitted, but the usefulness of the comparison may be greatly reduced. 4.9 For identification of composite materials, Table 1 (Part A) and Tables 2 and 3 shall be used. (A) Includes non-hexagonal open cell shapes, such as Flexcore®, etc. Flexcore® is a registered trademark of Hexcel, Inc. and has been found satisfactory for this purpose. 4.10 For identification of fiber, filler, and core, Table 1 (Part B), Tables 4- 10 , and Tables 11- 14 shall be used. (A) Field numbers are for information only. (B) Dimension parameter and value should be given for each relevant dimension. Type is essential information if value is given. (C) For each dimension in which distribution width is relevant. Parameter is essential if parameter value is given. 4.11 For identification of matrix, Table 1 (Part C) and Tables 15- 17 shall be used. (A) CMH-17, Volume 2, Section 1.6.1, and Terminology D1600 . 4.12 For identification of preform, Table 1 (Part D) and Tables 18- 20 shall be used. 4.13 For identification of prepreg, Table 1 (Part E), Table 5 , and Tables 21 and 22 shall be used. 4.14 For identification of process, Table 1 (Part F), Table 16 , and Tables 23- 26 shall be used. 4.15 For identification of composite parts, Table 1 (Part G) and Table 27 shall be used.
