What are the Carbon Fiber

A Carbon Fiber is a fibrous carbon material having a micro graphite crystal structure made by fibrillation of Acrylic resin, a well known textile material, or from oil/coal pitch and then by being given a certain heat treatment.

Hign Tensile Strength or Modulus

PAN Type Carbon Fiber A type of the fiber, produced by carbonization of PAN precursor

(PAN: Polyacrylonitrile), having high tensile strength and high elastic modulus, extensively applied for structural material composites in aerospace and industrial field and sporting /

recreational goods.

Pitch Type Carbon Fiber Another type of the fiber, produced by carbonization of oil / coal pitch precursor, having extensive properties from low elastic modulus to ultra high elastic modulus. Fibers with ultra high elastic modulus are extensively adopted in high stiffness components and various uses as utilizing high thermal conductivity and / or electric conductivity.

Light in weight, Strong and Durable!" Carbon Fibers are nothing but a 21st. century high

technology material. The fibers have specific gravity, exquisite mechanical properties

(high specific tensile strength, high specific elastic modulus, etc.)

ttractive performances

(electric conductivity, heat resistance, low thermal expansion coefficient, chemical stability, self-lubrication property, high heat conductivity, etc.)

Those features have been stimulating Carbon Fiber users to develop numerous kinds of applications
