The purpose of this document is to provide a minimum set of fracture control requirements to be used in designing and assessing composite and bonded structures. These requirements were developed to provide a minimum set of fracture control requirements to be used across MSFC programs in designing and assessing composite and bonded structures. 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. It is applicable to in-house and contract activities. These requirements have been developed under the auspices of the MSFC Fracture Control Board. 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.
