本文件提供了用于制造MSFC载人飞行器和有效载荷硬件的复合材料和粘结结构的断裂控制要求。范围包括载人发射、回收、转移和着陆飞行器、空间栖息地，以及在载人航天任务的任何部分中发射、回收、储存或运行的有效载荷或实验。纤维增强聚合物基复合材料、夹层结构（粘结金属和非金属）以及金属或复合零件之间的粘结属于本文件的范围。金属和陶瓷基体结构、泡沫、柔性充气结构、液体燃料火箭发动机和固体推进剂除外。此外，本文件未具体涵盖金属零件/结构的断裂控制，但如果金属与复合材料或粘合剂结合使用，则应满足本文件的所有规定。

This document provides the fracture control requirements for composite and bonded structures used in the construction of MSFC manned vehicle and payload hardware. The scope includes manned launch, retrieval, transfer, and landing vehicles, space habitats, and payloads or experiments that are launched, retrieved, stored, or operated during any portion of a manned spaceflight mission.Fiber reinforced polymer matrix composites, sandwich construction (bonded metallic and nonmetallic), and bonds between metallic or composite parts fall within the scope of this document.Metal and ceramic matrix structures, foam, flexible inflatable structures, liquid-fueled rocket engines, and solid propellants are specifically excluded. Also, fracture control of metallic parts/structures are not specifically covered by this document, but where metallics are used in conjunction with composites or bonds, all the provisions of this document shall be met.
