1. Light Weight Materials in Space Shuttle Presentation by Dr. Muhammad Kashif Khan Manager (Design & Development) SUPARCO October 2011

2. 1- Introduction Spacecraft flight- A fascinating story for children and adults Countless benefits of space technology Space engineering is not only limited to discovery of planets, stars, moons etc.

3. 2- Use of Space Engineering Better understanding of universe Weather prediction Communication Possible risks for earth Estimated life of our planet

4. 3- Effect of Space Environment on Materials Vacuum Radiation Temperature Thermal Cycling Atomic oxygen Micrometeoroids & Debris

5. 3- Effect of Space Environment on Materials Space environment cause: i.Release of gases from materials ii.Corrosion iii.Radiations of sun which degrades the material properties iv.Space Debris

6. 4- Development of Space Shuttles & Satellites Weight saving an important criteria A single gram additional can cause extra-ordinary additional cost and energy One gram of additional weight to space may cost extra several thousand dollars Need of light weight but strong structures

7. 4- Development of Space Shuttles & Satellites Space environment cause : i.Release of gases from materials ii.Corrosion iii.Radiations of sun which degrades the material properties iv.Space Debris

8. 5- Light Weight Materials for Space Shuttle Metals Steel Aluminum Magnesium Copper Titanium Mars Rover of TitaniumAluminum plates

9. 5- Light Weight Materials for Space Shuttle Composites Carbon Fiber Glass Fiber Aramid Fiber Different clothes of Glass Fiber

10. 5- Light Weight Materials for Space Shuttle Foams Polyurethane PVC PMI EPS PU Foams EPS Foams

11. 5- Light Weight Materials for Space Shuttle Carbon-Nanotubes Single Walled Double Walled Possess excellent combination of physical, electrical and thermal properties. An attractive option for structural integrity of high performance structures. Single-Walled CNTDouble-Walled CNT

12. 5- Light Weight Materials for Space Shuttle Sandwich Materials Used extensively in space missions Cores of light weight materials like Al, Foam, Wood, Paper etc. Thin top and bottom layers of strong materials like Al, Carbon Fiber etc. are used

13. 5- Light Weight Materials for Space Shuttle Paints Used for surface protection Thermal control sub-systems Corrosion protection Identification of components
