Carbon fibers

Carbon fibers began to be produced on a modern scale in the mid-20th century. They were first used in the 1960s in the aerospace and space industries. Carbon is a material with very high mechanical strength and low weight. Carbon fiber, formed by aligning and processing carbon atoms into extremely fine filaments, stands out due to its exceptional strength and lightness. Carbon fibers are typically combined with polymer matrices to create composite materials, which are preferred in various industrial applications. Carbon fibers are prominent materials due to their high strength, low weight, corrosion resistance, and flexible design possibilities.

Carbon fibers are produced by carbonizing a polymer-based precursor material, such as polyacrylonitrile (PAN) or petroleum pitch, at high temperatures. During the production process, the fibers are structured to have a regular and crystalline arrangement, achieving high strength and elasticity. The high energy requirements and precise technical methods involved in production are key factors that increase the cost of carbon fibers.

Carbon fibers are widely used, especially in the aerospace and space industries. They are employed in spacecraft equipment, commercial aircraft tail and wing structures, helicopter fuselages, and engine components. In commercial applications, they are used in automotive parts, sports equipment, wind turbine blades, and racing bicycles. The superior mechanical properties of carbon fibers make them indispensable in applications requiring advanced technology.

• Lightweight: Carbon fiber is much lighter than steel, a feature that contributes to fuel savings, especially in the transportation and automotive sectors.
• High Strength: Carbon fiber possesses high strength and elasticity, making it durable under demanding conditions.
• Corrosion Resistance: Carbon fiber is resistant to chemicals and does not suffer from issues such as rusting.
• High Thermal Resistance: Carbon fiber is resistant to high temperatures and is therefore preferred in applications where heat resistance is critical.

• High Cost: Carbon fiber production is expensive, so products made from carbon fiber are generally costly.
• Brittleness: Although carbon fiber can withstand high forces, it can be brittle under sudden impacts and is susceptible to cracking.
• Complex Production Process: The production of carbon fiber is complex and time-consuming, increasing both production time and costs.
