Fibre-reinforced plastic composites — Standard qualification plan (SQP) for composite materials, including reduced qualification plan (RQP) and extended qualification plan (EQP) schemes 纤维增强塑料复合材料.复合材料的标准鉴定计划(SQP) 包括简化鉴定计划(RQP)和扩展鉴定计划(EQP)计划
发布日期: 2019-07-12
1.1本文件规定了复合材料初步鉴定的程序,以便进行质量控制、材料选择和初步设计。与针对不同定制用户需求的多个双边鉴定相比,它提供了一个单一的程序,允许更快、更低成本的鉴定。本文档侧重于开发基于B的设计许用。 1.2该程序包括标准鉴定计划(SQP),其中包括更高各向异性复合材料的最低通用测试要求。扩展资格计划(EQP)包含进一步的测试要求,其中包括代表特定在役功能的选项。简化鉴定计划(RQP)方案使用与SQP相同的测试板制备核心结构和测试方法,可用于各向异性较低且倾向于名义各向同性的复合材料。1.3该程序适用于用于结构或半结构应用的纤维增强热固性和热塑性材料系统。本文件中提及的单个测试方法标准提供了关于每种情况下所涵盖的复合材料的类别和类型的更多细节。 1.4包括附件A和B,以支持在一致的数据库中显示获得的数据,并分别提供用于确定B基准设计允许量的统计程序。
1.1 This document specifies a procedure for the initial qualification of composite materials in order to allow quality control, material selection and preliminary design to be undertaken. It provides a single procedure allowing quicker and lower cost qualification compared to multiple bi-lateral qualification against different bespoke user needs. This document focuses on developing B-basis design allowables. 1.2 The procedure comprises a standard qualification plan (SQP) that includes the minimum common test requirements for more highly anisotropic composite materials. Further test requirements are encompassed in an extended qualification plan (EQP), which includes options representing specific in-service features. A reduced qualification plan (RQP) scheme, using the same core structure of test plate preparation and test methods as the SQP, is available for less highly anisotropic and tending towards nominally isotropic composite materials. 1.3 The procedure is suitable for fibre-reinforced thermoset, and thermoplastic, based material systems intended for structural or semi-structural applications. Individual test method standards referred to in this document provide more details as to the classes and types of composite materials that are covered in each case. 1.4 Annexes A and B are included to support presentation of the data obtained in a consistent database and to provide statistical procedures for the determination of B-basis design allowables, respectively.
