The Difference Between Carbon Fiber And Carbon Fiber Composites

The Difference Between Carbon Fiber And Carbon Fiber Composites

Carbon fiber, carbon fiber composite materials, some friends will confuse them, do not understand whether they are the same material or different materials, what are the differences or similarities. In this article, I will give you an answer, I hope it will be helpful to you after reading it.

Carbon fiber is a fiber material with a carbon content of more than 90%. It is obtained by oxidizing and carbonizing polyacrylonitrile fiber, pitch fiber, viscose fiber, etc. at a high temperature of several thousand degrees Celsius. It is very slender and has a diameter of only hair. One twentieth, with high strength, low density, high temperature resistance, corrosion resistance, friction resistance, low thermal expansion coefficient and other advantages.

At present, few countries have mastered the production methods of carbon fiber precursors, especially carbon fibers with ultra-high strength and ultra-high modulus, which are state secrets and will not be announced to the public.

Definition Of Carbon Fiber Composites And Carbon Fiber

Carbon fiber is a high-performance fiber material, mainly composed of carbon elements. It has excellent properties such as light weight, high strength, and high stiffness. It is widely used in aerospace, ships, automobiles, sports equipment and other fields. Carbon fiber composites are a new material that combines carbon fiber with a matrix (such as resin, metal, etc.) and other additives. It has richer performance and usage scenarios than carbon fiber.

The Difference Between Carbon Fiber Composite Materials And Carbon Fiber

  • Different composition materials: Carbon fiber composite materials are composed of a variety of materials. In addition to carbon fiber, they also need a matrix and other additives; while carbon fiber is a fiber material composed purely of carbon elements.
  • Different performance: Carbon fiber composite materials have the advantages of high strength and high stiffness of carbon fiber, as well as the corrosion resistance and wear resistance of the matrix. In different application scenarios, carbon fiber composite materials can choose different matrices and additives to meet specific needs; while carbon fiber can only meet some application scenarios with relatively single performance requirements.
  • Different processing techniques: Preparing carbon fiber composite materials requires multiple processes, including prepreg, automatic shaping, curing and other processes; while carbon fiber only requires simple processes such as spinning and heat treatment.

Carbon fiber composite material is a prototype material made of carbon fiber filaments combined with resin, ceramics, carbon, plastic, metal, etc. It has strong plasticity and can be made into a variety of products. It is widely used in military sheet metal fabrication and civilian industries. The carbon fiber plates, carbon fiber tubes, carbon fiber auto parts, and carbon fiber wallets that we usually hear are actually made of carbon fiber resin composite materials, and carbon fiber raw materials are rarely used alone. Because it is a composite of various raw materials, there is still a certain difference in performance and carbon fiber raw materials.  

There are few manufacturers of carbon fiber precursors, but there are many manufacturers that can process carbon fiber composite products. Domestically, they are mainly concentrated in the Yangtze River Delta and the Pearl River Delta. China Rapid Prototype company is located in the economically developed Dongguan China. It has been established for many years and has mastered a variety of machining and forming technologies. The equipment is imported from abroad, the product quality is high, and it has cooperation with units.


ISO 9001 certified. BE-CU Prototype Offering CNC machining carbon fiber and other manufacturing services for carbon fiber marterial. Various capabilities include notching, labeling, drilling carbon fiber, grinding, laser cutting carbon fiber, finishing, plating, marking, CNC milling carbon fiber and turning carbon fiber.We stock high quality 3k carbon fiber sheet in a variety of thickness, types and finish. Its a great material used in applications where light weight and strength are needed such as drones. Unlike other workshops, we have no min order and are often filling orders with a single part. We also don’t make you pay for the full sheet and you only get charged for what is used. With a large selection of material, you should find everything you need to make your project come to life. We are also able to handle larger production runs and provide a competitive pricing. If we don’t have the material or finish you require, we are more the willing to look at bringing it in for you.
