Materials and Manufacturing - NASA

To build a spacecraft, we must begin with Materials . Sometimes the Materials and material choice is the solution. Other times, the design must Manufacturing accommodate the limitations of Materials properties. The design of the Space Shuttle systems encountered many material challenges, such as Introduction weight savings, reusability, and operating in the space environment. Gail Chapline NASA also faced Manufacturing challenges, such as evolving federal Nondestructive Testing Innovations regulations, the limited production of the systems, and maintaining Willard Castner flight certification. These constraints drove many innovative Materials Patricia Howell solutions. Innovations such as large composite payload bay doors, James Walker Friction Stir Welding Advancements nondestructive Materials evaluation, the super lightweight tank, and Robert Ding the understanding of hydrogen effects on Materials were pathfinders Jim Butler used in today's industry.

tiles were structurally sound prior to installation. Evaluation of pulse or sonic velocity tests showed a velocity relationship with respect to both tile density and strength. These measurements could be used as a quality-control tool to screen tiles for low density and low strength and could also determine the orientation of the tile.
