GB/T 32303-2015 Active

This standard specifies the minimum requirements for fracture control and mechanical damage control in general aerospace structures, including launch vehicles and spacecraft. Reusable launch vehicles may refer to this standard for implementation. This standard aims to standardize the application of fracture control technology and mechanical damage control technology in aerospace structures, ensuring that aerospace systems achieve a high level of reliability and safety during operation and use, and guaranteeing the success of aerospace missions. This standard applies to metal, non-metal, or composite structures where fracture is the main failure mode, as well as composite structures that may suffer mechanical damage and consequently lead to a decrease in bearing capacity or even premature failure. This standard does not apply to the treatment of known defects.
