Carbon Fiber Tow
(Continuous fiber)
Carbon fiber is a high-strength and high-elastic modulus material, yet its specific gravity is only one-fourth that of iron. It, therefore, enables high strength, high rigidity, and weight-saving in a wide variety of applications.
Carbon fiber tow, made of bundles of untwisted filaments, is the essential material in our carbon fiber product line.

Features
Mitsubishi Chemical manufactures both PAN-based and pitch-based carbon fiber materials.
Thanks to our unique ability to manufacture carbon fiber from two basic raw materials, PAN and pitch, in comprehensive, streamlined production systems, we offer a variety of high-quality carbon fiber tow, including ultra-high strength (MR70 12P) and ultra-high modulus (K13D2U) materials.
The raw material fiber (precursor) for PAN-based carbon fiber is made using polyacrylonitrile (PAN) as a raw material. The raw PAN is polymerized utilizing Mitsubishi Chemical’s unique expertise in polymer synthesis and polymer processing technologies and then spun.
The raw material fiber for pitch-based carbon fiber is produced by obtaining coal tar pitch from coal utilizing Mitsubishi Chemical’s longstanding knowledge of coal chemistry, processing the pitch using an original process, and finally spinning the pitch.
Carbon fiber tow is produced by carbonizing these raw fibers in a highly controlled environment.
Mitsubishi Chemical has also acquired quality management system certification (JISQ9100) in the field of aviation, aerospace, and defense, and it constantly strives to improve its quality management system further.
Applications
Carbon fiber tow is processed into various forms and combined with matrix resin to use like carbon fiber reinforced plastics (CFRP). Products made from CFRP exhibit high-strength, high-elastic modulus, and lightweight, a combination of properties unique to carbon fiber.
