Carbon Fiber vs. Fiberglass

By Sara Langevin, Adam Ferrara, and Aidan Clendening.

What are Carbon Fiber and Fiberglass?

Carbon Fiber: A material consisting of thin, strong crystalline filaments of carbon, used as a strengthening material, especially in resins and ceramics.

Fiberglass: a reinforced plastic material composed of glass fibers embedded in a resin matrix.

What's the difference?

Carbon Fiber blocks radio signals while fiberglass doesn't. Carbon Fiber is lighter than fiberglass. Carbon fiber and fiberglass are both very strong, but Carbon fiber is more rigid. Fiberglass is more flexible than Carbon Fiber. Carbon Fiber doesn't expand or shrink as much as fiberglass. Fiberglass is less expensive than carbon fiber. Long strands of carbon fibers are very difficult and expensive to manufacture, while fiberglass is much easier to make. Fiberglass is also natural.


Many people say that Carbon Fiber is better because it's stronger, but it is bad for the earth. Carbon fiber hurts the earth because it's difficult to manufacture, but is stronger and lighter. Fiberglass is less expensive but isn't as sturdy. We think that fiberglass is better because it's better for the earth. Carbon fiber is hard to manufacture(it needs more manufacturing). Manufacturing is bad for the earth because it releases smoke from the factories and that ruins the air.
