Fracture Control Requirements for Composite and Bonded Structures

Current new requirements document are top level or specific to shuttle payloads. NASA-STD-5007 top level requirement that imposes fracture control on all manned spacecraft hardware. Composites addressed at very top level. NASA_SDT-5003 imposes fracture control on payloads for the space shuttle. Imposes fracture control on composite and bonded structures. Silent on many important issues such as post proof NDE, residual strength, and reuse. Not adequate for or directly applicable to next generation of spacecraft.

Space Tethers Design Criteria

The small expendable deployable system and tether satellite system programs did not have a uniform written criteria for tethers. The JSC safety panel asked what criteria was used to design the tethers. Since none existed, a criteria was written based on past experience for future tether programs.
