has a series of excellent properties such as high strength, high modulus, corrosion resistance, and small thermal expansion coefficient, so its application fields are very wide. In order to meet customer needs, carbon fiber manufacturers have developed a variety of fibers for different purposes to make full use of the excellent properties of carbon fibers. This article will comprehensively analyze 10 application methods and uses of carbon fiber products. 1. Continuous long fiber
Product features: The most common product form of carbon fiber manufacturers, the tow is composed of thousands of monofilaments, divided into three types according to the twisting method: NT (Never Twisted, untwisted), UT (Untwisted, untwisted), TT or ST (Twisted, twisted), among which NT is the most commonly used carbon fiber. For twisted carbon fiber
, according to the twist direction, it can be divided into S-twisted yarn and Z-twisted yarn (as shown in the figure below).
Main application: mainly used for composite materials such as CFRP, CFRTP or C/C composite materials, and the application fields include aircraft/aerospace equipment, sporting goods and industrial equipment parts. 2. Short fiber roving
Product Features: Spun yarn for short, the yarn spun from short carbon fiber, such as general-purpose pitch-based carbon fiber, is usually in the form of short fiber.
Main application: heat insulation materials, anti-friction materials, C/C composite parts, etc.
3. Carbon fiber fabric
Product features: It is woven from continuous carbon fiber or short carbon fiber roving. According to the weaving method, carbon fiber fabric
can be divided into woven fabric, knitted fabric and non-woven fabric. At present, carbon fiber fabric is usually woven fabric.
Main use: Same as continuous carbon fiber, mainly used for composite materials such as CFRP, CFRTP or C/C composite materials, and the application fields include aircraft/aerospace equipment, sporting goods and industrial equipment parts.
