Prototype #3: Materials Exploration

My original concept for prototype #3 was to make it as stiff and light as possible.  So I experimented with carbon fiber and kevlar combination as the main material.  Kevlar has great vibration dampening characteristics and is more inexpensive compared to carbon fiber. 

I did multiple experiments to see how many layers of kevlar I need and ways to make it stiffer without adding added weight.  By adding ribs or using sandwiching techniques, I was able to make it rigid and light.
