1 Scope

1.1 This document specifies methods for initial qualification of composite materials for quality control, material screening and preliminary design. Used differently with

Compared with providing customized multiple bilateral authentications based on user needs, this document provides a low-cost, high-efficiency single authentication method. This document focuses on

Determine the allowable value of B basis design.

1.2 This document provides the Standard Qualification Program (SQP), Extended Qualification Program (EQP) and Reduced Qualification Program (RQP) for composite materials.

SQP includes the lowest general test requirements for composite materials with obvious anisotropy; EQP provides higher test requirements, including the selection of tools.

Representative service performance; RQP is suitable for composite materials with little anisotropy and nominal isotropy. Its test plate preparation and testing

The core part of the verification method is the same as SQP.

1.3 This document applies to fiber-reinforced thermoset and fiber-reinforced thermoplastic composite materials used as structural or sub-structural components. This article

The article gives the composite material types applicable to each test method under different test conditions.

1.4 Appendix A provides a report sheet that unifies the expression of test data. Appendix B provides a system for determining the allowable values of B-base design.
