According to the material, carbon fibers were developed by whom?

• A. Thomas Edison
• B. Nikola Tesla
• C. Marie Curie
• D. Alexander Graham Bell

Answer: (A)

Carbon fibers in this material are tied to Thomas Edison because his extensive work on carbon-based filaments for electric lighting showed that carbonized fibers could be made to carry load and withstand heat. This line of investigation demonstrated how carbon, when processed through controlled heat treatment, could become a strong, lightweight filament. Those early experiments laid the groundwork for thinking of carbon forms as reinforcement materials, which later evolved into the carbon fiber reinforcements used in modern composites. The other famous inventors listed are known for different breakthroughs, not for developing carbon fibers as described here.
