Why is carbon fiber material favored across various fields?

Speaking of carbon fiber, it is now almost universally known. It is used in military security, medical devices, automotive manufacturing, sporting goods and other industries. With the development of technology, the fields involved are constantly increasing. Why do people like to use carbon fiber to manufacture products? How did it develop? What are its advantages?

Carbon fiber is now almost universally known and used in various industries, including military security, medical devices, automotive manufacturing, and sporting goods. With advancing technology, its applications continue to expand. Why is carbon fiber so popular in product manufacturing? How did it evolve, and what are its advantages?

Initially, carbon fiber wasn't as valued as it is today, primarily used as filaments in light bulbs. After the invention of tungsten filaments, it fell into disuse. Later, driven by wartime needs, scientists experimented with various materials and found carbon fiber suitable for military applications. Subsequently, its use expanded to other areas, from high-tech aircraft and yachts to everyday items like pen casings, belt buckles, and wallets.

Carbon fiber's advantages include high-temperature resistance, corrosion resistance, high strength-to-weight ratio, and high tensile modulus. Its strength is over four times that of steel, yet it weighs only one-tenth as much, making it superior to metals. However, it has a drawback: high brittleness, making it susceptible to fracture under concentrated, high loads.

Carbon fiber's popularity stems from its alignment with modern demands. Products today need to meet not only functional needs but also high-performance standards. For example, the automotive industry focuses on lightweight designs, a goal perfectly suited to carbon fiber. Its future applications are expected to be even broader.
