What are the material characteristics of carbon fiber products

Carbon fiber products refer to carbon fiber prepreg cloth as raw material, through different treatment methods, the treatment materials can meet the requirements of the product. Due to the high material properties of carbon fiber, the strength and hardness of carbon fiber products are much higher than those of metal materials in terms of volume and weight. 1. A quarter of the weight and volume of carbon fiber is equal to steel. 2. The strength of carbon fiber products is equal to ten times the same volume of aluminum.

Is carbon fiber a synthetic material or a composite material?

Is carbon fiber a synthetic material or a composite material?

Carbon fiber belongs to composite materials. Because carbon fiber not only has the inherent characteristics of carbon materials, but also has the flexibility and processability of textile fibers, it is a new generation of reinforcing fibers, so it is a composite material. Carbon fiber: Carbon fiber (CF) is a new type of fiber material with high strength and high modulus and a carbon content of over 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fibers and undergoing carbonization and graphitization treatment. Carbon fiber is "flexible outside and rigid inside", lighter in weight than aluminum metal, but higher in strength than steel. It has corrosion resistance and high modulus characteristics, and is an important material in national defense, military industry, and civil applications. It not only has the inherent characteristics of carbon materials, but also has the flexibility and processability of textile fibers. It is a new generation of reinforcing fibers.

Carbon fiber material properties

Carbon fiber material properties

In the large family of composite materials, fiber reinforced materials have always been the focus of attention. Since the advent of fiberglass reinforced plastics (GRP) reinforced with glass fiber and organic resin, carbon fiber, ceramic fiber, and boron fiber reinforced composites have been successfully developed, and their performance has been continuously improved, making the field of composite materials show a vibrant vitality. Let's take a look at the unique carbon fiber composite materials. Carbon fiber is a special type of fiber mainly composed of carbon elements, and its carbon content varies with the type, generally over 90%. Carbon fibers have the characteristics of ordinary carbon materials, such as high temperature resistance, abrasion resistance, electrical conductivity, thermal conductivity, and corrosion resistance. However, unlike ordinary carbon materials, their appearance is significantly anisotropic, flexible, and can be processed into various fabrics, exhibiting high strength along the fiber axis. Carbon fibers have a small specific gravity and therefore have high strength. Carbon fiber is made of man-made chemical fibers with a high carbon content that do not melt during heat treatment, and is processed through heat stable oxidation, carbonization, and graphitization. The main use of carbon fibers is to composite with matrices such as resins, metals, and ceramics as well as to make structural materials. Carbon fiber reinforced epoxy resin composites have high specific strength and specific modulus among existing structural materials. Carbon fiber composites have advantages in areas with strict requirements for stiffness, stiffness, weight, and fatigue properties, as well as in situations requiring high temperature and chemical stability. Carbon fiber was produced in the early 1950s in response to the needs of cutting-edge science and technology such as rockets, aerospace, and aviation. It is now widely used in sports equipment, textiles, chemical machinery, and medical fields. With the increasingly stringent requirements of cutting-edge technology on the technical performance of new materials, scientific and technological workers are constantly striving to improve. In the early 1980s, high-performance and ultra-high-performance carbon fibers emerged one after another, which was another technological leap, marking that the research and production of carbon fibers had entered an advanced stage.

What is carbon fiber used for

What is carbon fiber used for

Different uses, main features, and classifications. 1. Different uses. The main use of carbon fiber is to composite with resins, metals, ceramics, and carbon as a reinforcing material to manufacture advanced composite materials. Carbon fiber reinforced epoxy resin composites have high specific strength and specific modulus among existing engineering materials. Carbon is mainly used as a conductive anode for ultra high power steelmaking electric arc furnaces, electrolytic equipment in the electrochemical industry, and in aerospace, electronics, and nuclear industries. The differences between carbon and carbon fiber include different uses, main characteristics, and classifications. 1. Different uses.

The main characteristics are different. Carbon fibers have characteristics such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity, and corrosion resistance. Their appearance is fibrous, soft, and can be processed into various fabrics. Due to the preferred orientation of their graphite microcrystalline structure along the fiber axis, they have high strength and modulus along the fiber axis. Carbon fibers have a low density and therefore a high specific strength and specific modulus. Carbon has light weight, porosity, conductivity, thermal conductivity, corrosion resistance, lubricity, high temperature strength, heat resistance, thermal shock resistance, low thermal expansion, low elasticity, high purity, and processability. 3. Classification is different. The main products of carbon fibers include three categories: polyacrylonitrile based, asphalt based, and viscose based. Each category of products is divided into many varieties due to different types of raw fibers, processes, and final carbon fiber properties. Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger, etc. according to product usage. Graphite electrodes can be divided into ordinary power graphite electrodes based on the allowable current density.

How to make carbon fiber?

How to make carbon fiber?

Carbon fiber material is wrapped in layers of carbon cloth, with adhesive between each layer. It is pre oxidized in air at 200 to 300 ℃, then carbonized under inert gas protection at a high temperature of about 1000 ℃, and finally heated to 1500 to 3000 ℃ to form carbon fiber. Viscose is toxic, and carbon fiber debris is very fine, which can seriously affect health if inhaled into the lungs. It is not recommended to use this product yourself Carbon fiber is a new type of fiber material with high strength and high modulus fibers with a carbon content of over 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fibers and undergoing carbonization and graphitization treatment.
