Introduction goes here

The selection process

• Design requirements - Maximum stiffness/weight ratio - Minimum cost - Easy manufacture

What we’re aiming for

Cost

Stiffness/Weight

A bit about nanotubes????

Composite SandwichPros:• 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
