Advantages && Disadvantages Of Carbon Fiber

Advantages of Carbon Fiber

Carbon fiber composites stand out from the crowd for several reasons. Here are a few:

  • Lightweight – carbon fiber is a low density material with a very high strength to weight ratio

  • High tensile strength – one of the strongest of all commercial reinforcing fibers when it comes to tension, carbon fiber is very difficult to stretch or bend

  • Low thermal expansion – carbon fiber will expand or contract much less in hot or cold conditions than materials like steel and aluminum

  • Exceptional durability – carbon fiber has superior fatigue properties compared to metal, meaning components made of carbon fiber won’t wear out as quickly under the stress of constant use

  • Corrosion-resistance – when made with the appropriate resins, carbon fiber is one of the most corrosion-resistant materials available

  • Radiolucence – carbon fiber is transparent to radiation and invisible in x-rays, making it valuable for usage in medical equipment and facilities

  • Electrical conductivity – carbon fiber composites are an excellent conductor of electricity

  • Ultra-violet resistant – carbon fiber can be UV resistant with use of the proper resins


  • Carbon fiber will break or shatter when it’s compressed, pushed beyond its strength capabilities or exposed to high impact. It will crack if hit by a hammer.  Machining and holes can also create weak areas that may increase its likelihood of breaking.

  • Relative cost – carbon fiber is a high quality material with a price to match. While prices have dropped significantly in the past five years, demand has not increased enough to increase the supply substantially. As a result, prices will likely remain the same for the near future.
