In the field of advanced materials, carbon fiber exemplifies strength, lightness, and versatility. From aerospace to automotive, sporting goods to architecture, this extraordinary material has revolutionized a wide range of industries. In this article, we’ll explore what is carbon fiber material, its unique properties, and the myriad applications that make it such an important part of modern technology and design.
What is carbon fiber material?
Carbon fiber is a high-strength, high-modulus fiber containing more than 90% carbon. It is mainly composed of carbon elements and uses acrylic and viscose fibers as raw materials. It is an excellent material with super high strength.
How carbon fiber is made?
There are a total of three manufacturing methods for carbon fiber materials: wet lay-up, prepreg lamination, and resin transfer molding.
Wet lay-up: The fibers will first be cut and laid into a mold, and resin will be added via brush or gun.
Prepreg lamination: This is done by injecting resin, which is then kept refrigerated until it cures. It is then heated and cured under pressure in an autoclave.
Resin transfer molding: After molding into a mold, the resin is pressed under high pressure.
Characteristics of carbon fiber
Carbon fiber is also a popular material because of the following characteristics:
High Temperature Resistance: This material can be used at temperatures up to 400 °C and still maintain stable performance.
Strength: Carbon fiber has a tensile strength of 2.2 GPA, which is much higher than metal, making it an excellent choice for applications that require a high strength-to-weight ratio.
Lightweight: Carbon fiber has a density of approximately 1.6-2.5/cm3, which is much lighter than steel, at approximately 7.85 g/cm3.
Rigidity: Carbon fiber has a high modulus of elasticity, which allows it to withstand large bends and deformations without breaking.
Corrosion Resistance: Carbon is one of the most stable elements and will not corrode, making it ideal for applications in harsh environments where there is constant exposure to moisture and chemicals.
Electrical and Thermal Conductivity: Depending on the orientation of the fibers, carbon fibers can have varying degrees of electrical and thermal conductivity.
X-ray Transparency: Carbon fiber is transparent to X-rays, making it useful in medical imaging equipment and other applications requiring non-metallic materials.
Types of carbon fiber
Carbon fiber materials can be divided into general purpose, high strength, medium mode high strength, high model, and ultra-high model carbon fibers according to their properties. This classification represents in order from low to high tensile strength and tensile modulus.
Carbon fiber application areas
The high-quality performance of carbon fiber has led to its use in a wide range of industries:
- Aerospace: Carbon fiber is often used as a primary load-bearing structure. It is used in aircraft components to reduce weight and save fuel for improved efficiency.
- Marine: This material is commonly used in the manufacture of propeller blades and propulsion systems. It can effectively improve the structure, energy consumption, and maneuverability of ships.
- Automotive: Carbon fiber is used in high-performance and luxury cars to reduce weight and increase compressive strength and road feel.
- Sporting Goods: Tennis rackets, golf clubs, and bicycles benefit from the strength and lightweight properties of carbon fiber materials.
- Construction: Carbon fiber is used to reinforce concrete, as well as in structural applications for building curtain walls and bridges.
- Power cables: Aluminum conductors made with carbon fibers increase the ability to pass current and improve the reliability of power networks.
- Medical Devices: Carbon fiber’s X-ray transparency and strength make it suitable for medical imaging equipment and prosthetics.
- Defense and Security: The strength and corrosion resistance of this material make it ideal for military and security applications such as body armor and vehicle protection.
