2. Introduction goes here

3. The selection process Design requirements - Maximum stiffness/weight ratio - Minimum cost - Easy manufacture

4. What were aiming for

5. A bit about nanotubes????

6. Composite Sandwich Pros: Provides descent stiffness/weight Easy to manufacture Good crack dissipation Cheap Cons: Foam/honeycomb provide better stiffness/weight ratio Does not fully use the 3cm available

7. Our Fibre Metal Laminate Al 2024 Al Mesh (crack dissipation) Carbon Fibre Weave Al 2024 CF weave CF weave Al 2024

8. Foam and other cores.. Why not?
