100% Full Carbon Fiber (not sandwich structure) - A Truly Remarkable Material                                    

The first time you hold a carbon fiber part, you will be amazed at how light, yet stiff, it is. It is twice as stiff as high-strength aluminum alloys with an ultimate tensile strength that exceeds that of steel, yet it is the weight of plastic.
