<human>:  What's the Difference between carbon fiber and fiberglass?
<bot>: Carbon fiber is a strong and lightweight material made out of strands of carbon atoms, whereas fiberglass is a lightweight material made out of tiny glass fibers spun into yarns and then woven into a fabric. The carbon fibers used to make carbon fiber are much thinner than the strands of glass used to make fiberglass. As a result, carbon fiber objects are much lighter than those made of fiberglass of the same size, but they are also much stronger. This makes carbon fiber an ideal material for applications where weight and strength are important, such as aerospace, automotive, and sporting goods.
