An arrow is designed for strength while a bike is designed for light weight. Your carbon fiber composite arrow, if you sized it up to be the size of a bike, will weigh more than a department store huffy. A bike frame, if you scaled it down to be the size of an arrow, will be weaker than a chinese restaurant wooden chopstick.
That's beside the point....arrows used to be made of aluminum....some still are but no serious shooter uses them because carbon arrows are lighter, stronger and perform better in almost all normal arrow applications. Just like carbon bikes are lighter, stonger and perform better than aluminum, steel and ti bikes in almost all normal bicycle applications.
