Advantages of Carbon Fiber Product
Lightweight
Speaking of weight, carbon fiber is light! A carbon fiber reinforced plastic isn't much heavier than a non-reinforced plastic. When compared to steel, the overall weight reduction is about ninety percent. A 70 pound steel car hood can be re-created to weight a mere 7 pounds! It's lighter than aluminum and even titanium.
Suitable for a Variety of Uses
In addition to its extensive use in the high-end automotive world, carbon fiber is being applied in almost every field you can imagine. Hikers love its lightweight properties in backpacks and tents and drones, planes, and helicopters can significantly improve their power-to-weight ratios. Don't be surprised if carbon fiber pops up in a luxury RV, the emergency room, a musical instrument, or your next bicycle. In fact, CF has made products for each of those applications!
Doesn't Rust
Most materials react poorly to air and water, corroding, oxidizing, or simply breaking down unless protected. Not carbon fiber. Both the carbon and the epoxy resin are extremely stable and non-reactive, even when submerged in water! Ideal as a replacement for steel under conditions of extreme moisture or even submersion. There's no need for expensive anti-corrosion treatments or continual re-painting.
Transparent to X-Rays
Despite being stronger than steel, carbon fiber is totally transparent to x-rays. The medical applications for this are boundless, as no other material combines the strength of metal with the x-ray transparency of plastic. Imagine if instead of having to wheel a patient to a whole new room for an x-ray, they could simply be imaged live through an operating table!
Electrically Conductive
Carbon fiber filaments are electrically conductive, allowing the material to be used in applications like lightning strike protection. However, carbon fiber conductivity can potentially accelerate galvanic corrosion in fittings. This issue can be reduced by careful installation.
Types Raw Material of Carbon Fiber Product
PAN Type Carbon Fiber
A type of the fiber, produced by carbonization of PAN precursor (PAN: Polyacrylonitrile), having high tensile strength and high elastic modulus, extensively applied for structural material composites in aerospace and industrial field and sporting / recreational goods.
Pitch Type Carbon Fiber
Another type of the fiber, produced by carbonization of oil/coal pitch precursor, having extensive properties from low elastic modulus to ultra high elastic modulus. Fibers with ultra high elastic modulus are extensively adopted in high stiffness components and various uses as utilizing high thermal conductivity and / or electric conductivity.

Applications of Carbon Fiber Product
Aerospace – Carbon fiber is widely used in aerospace applications due to its high strength-to-weight ratio, stiffness, and corrosion resistance. Major uses include aircraft fuselages and wings, helicopter blades, rocket casings, and payload fairings. Using carbon fiber in airplanes can reduce weight by up to 20% for some aircraft. Barely Visible Impact Damage (BVID) is a disadvantage of employing carbon fiber in aircraft. This unseen damage has the potential to impact a component's safety. It requires a great deal of training and testing to detect BVID.
Automotive – As costs come down, carbon fiber is increasingly used in high-end and racing automobiles to reduce weight while maintaining strength and rigidity. Uses include body panels, hoods, roofs, spoilers, and structural components. Carbon fiber can help improve fuel efficiency and handling. Formula 1 race cars rely heavily on carbon fiber.
Sports Equipment – Many high-end bicycles now utilize carbon fiber frames and components to decrease weight and improve performance. Carbon fiber is also used for golf club shafts, tennis rackets, hockey sticks, and other specialty sports gear. In addition, carbon fiber hard hats, clothing, protective gear, and carbon fiber strain are examples of carbon fiber applications. Because racing sports often use carbon fiber helmets and shoes.
Civil Engineering – Carbon fiber reinforcing bars and cables can strengthen concrete and replace traditional steel reinforcement. This reduces the weight of concrete structures and increases their tensile strength. Carbon fiber wraps and laminates can strengthen structural elements like columns and bridges.
Consumer Electronics – Carbon fiber makes some high-end consumer electronics like laptops, phones, tablets, tripods, and headphones lighter and more durable. Carbon fiber device cases and structural components add strength and heat dissipation to these products. Also, the material is especially useful when electromagnetic transparency is needed.
Medical Devices – The biocompatibility and strength of carbon fiber have led to uses such as orthopedic implants, prosthetic limbs, and MRI machines. Carbon fiber-reinforced polymers allow precision parts like bone plates to be produced. Because carbon fiber appears transparent in X-ray images, it is used in various X-ray and imaging devices. Additionally, prosthetic limbs constructed from carbon fiber are strong, lightweight, and comfortable.
Manufacturing of Carbon Fiber Product
Like other materials, quality carbon fiber starts with a base component: polyacrylonitrile (PAN). 90% of carbon fibers are made out of that. The other 10% – petroleum pitch or rayon.
Manufacturers use a variety of liquids and gases to make carbon fiber. During the spinning, carbon fiber manufacturing PAN mixes with other ingredients to be spun into fibers. Then, fibers will wash and be stretched.
Next comes stabilizing. During this step, fibers being heating for 30-120 minutes to 390-590° F. A few things happen throughout this stage.
First, the fibers get the air's oxygen molecules. In doing so, the atomic bonding pattern rearranges over the course of chemical reactions. The techniques and equipment used in commercial stabilization processes vary from one process to another.
Some processes draw the fibers through heated chambers. Others pass them across hot rollers and through loose materials.
After stabilizing comes carbonizing. Stabilized fibers heat into a sweltering 1,830-5,500° F furnace for many minutes with an oxygen-less gas mixture. The absence of oxygen stops the fibers from burning.
Heating the fibers makes them drop their non-carbon atoms and even some carbon atoms. That takes the form of gases like ammonia, water vapor, carbon dioxide, carbon monoxide, nitrogen, hydrogen, and more. While the non-carbon atoms flee, the carbon atoms remaining make closely bonded carbon crystals.
