Carbon Fiber Filament Yarn

Carbon fiber tow yarn is a fiber material composed of carbon elements, usually formed by high-temperature carbonization of organic materials (such as polyacrylonitrile) through specific chemical and physical methods. The production process of this material involves multiple steps, including pretreatment, oxidation, and carbonization, to achieve high strength and lightweight characteristics in its structure. During this process, non carbon elements (such as hydrogen, oxygen, etc.) in the raw materials are removed, ultimately forming high-purity carbon fibers.

The diameter of carbon fiber tow yarn is generally small, ranging from a few micrometers to several tens of micrometers. Its production process requires strict temperature and atmospheres control to ensure that the quality and performance of the final product meet standards.

In summary, carbon fiber tow yarn is a type of fiber that has undergone special processing and manufacturing, mainly composed of carbon elements, and has specific production process characteristics.

Carbon fiber filament yarn is a continuous and extremely fine fiber. Its core component is carbon, which typically accounts for over 90% of its total mass. Carbon fiber filament yarn is the most basic and microscopic unit that constitutes all carbon fiber products (yarn, fabric, prepreg, composite materials). It can be imagined as an extremely small 'carbon filament'.
Carbon fiber filament yarn refers to carbon fiber products that have undergone specific processing, have stable performance, and longer lengths.

Carbon fiber filament yarn is a continuous carbon fiber material with high strength, high modulus, and lightweight properties. It is usually made from polyacrylonitrile fibers through processes such as pre oxidation, carbonization, and graphitization. Its diameter is only 5 microns (equivalent to ten to one twelfth of a human hair), but its strength can reach more than four times that of aluminum alloy. Long filament carbon fiber has excellent strength and rigidity, and can withstand large tensile forces, making it suitable for high-performance applications such as aerospace, military, and high-end sports equipment.

Carbon fiber filament yarn is a slender fiber composed of carbon element, usually made by high-temperature carbonization process of organic raw materials such as polyacrylonitrile, asphalt, etc. During its production process, the raw materials are heated in an oxygen deficient environment, which promotes the decomposition of organic matter and ultimately converts it into carbon. The diameter of carbon fiber filament yarn is generally between a few micrometers and several hundred micrometers, with high strength and rigidity. Due to its excellent structural and lightweight characteristics, carbon fiber filaments are widely used in various fields such as aerospace, automotive, and sports equipment.

Carbon fiber filament is a slender fiber composed of carbon-elements, usually made by high-temperature treatment (carbonization) of polymer precursors. The production process includes stretching and heat treatment of the fibers to arrange carbon atoms in an ordered structure within the fibers. The diameter of carbon fiber filaments is usually in the micrometer range, with high strength and rigidity, and exhibiting good heat resistance and chemical stability under certain conditions. Due to its manufacturing process and material characteristics, carbon fiber filament is widely used in various industrial and scientific research fields.

Carbon fiber yarn is essentially a continuous fiber bundle composed of thousands of extremely thin carbon fiber filaments bundled together, and is the most fundamental and important industrial intermediate form of carbon fiber materials. Its birth began with specific organic precursor fibers (the most common being polyacrylonitrile fibers, also known as PAN based, or asphalt based or adhesive based), which undergo a series of complex and precise high-temperature heat treatment processes, including pre oxidation (stabilized at 200-300 ° C in air), carbonization (expelling non carbonelements at 1000-2000 ° C in an inert atmospheres to form a disordered graphite structure), and possible graphitization (further optimizing crystal structure orientation and increasing modulus at higher temperatures such as 2500-3000 ° C). 

After these rigorous conversion processes, the original organic fibers undergo a complete transformation, with a carbon content of over 90% in their elemental composition, forming carbon fiber monofilaments with unique properties.

Carbon fiber yarn is a fiber material with a carbon content of 95% or more. Carbon fiber is “soft on the outside and strong on the inside”, lighter than aluminum metal, but stronger than steel, and has the characteristics of corrosion resistance and high modulus, which is an important material in many applications. It not only has the inherent characteristics of carbon material, but also has the soft processability of textile fiber.

Carbon fiber filament yarn is a high-performance carbon fiber product that significantly enhances and strengthens the properties of thermoset and thermoplastic composites. This includes products made for aerospace, automotive and several industrial applications. With a high tensile strength and tensile modulus, carbon fiber filament yarn is ideally suited for many processes, such as prepregging, filament winding, pultrusion, weaving and braiding.
