Carbon fibers, which are pitch-based, are imported from Japan in plastic packaging in a continuous non-woven mat form, measuring 150-200 feet in length by 40 inches in width. The imported continuous non-woven fiber is purchased for approximately $6.00 /lb.

This specialized pitch-based carbon fiber has a bending stiffness over 3 times that of a standard modulus prepreg panel (about 25 msi). When one considers the possibility of customized carbon fiber panel stiffness through strategic laminate placement, a panel (or other cross-section, such as a tube) can be fabricated with bending stiffness on ...

The carbon fiber is pitch-based. The characteristics of the material are: a low density thermal insulation product; an insulation material having high flexural strength and low thermal conductivity, an environmentally safe material.

Carbon fiber can have a broad range of CTE's, -1 to 8+, depending on the direction measured, the fabric weave, the precursor material, Pan based (high strength, higher CTE) or Pitch based (high modulus/stiffness, lower CTE).. In a high enough mast differences in Coefficients of thermal expansion of various materials can slightly modify the rig tensions.

Carbon fiber is a lightweight, flexible, high strength, high tensile modulus material produced from polyacrylonitrile (PAN), pitch, or rayon by a series of heating steps.

Despite lack of specification highlighting the considered contaminants to be expressed in a maximum of 1%, according to Baker, Griffith and Compere (2005), lignin-based carbon fiber requires methods to extract salts, particulate matter and volatile . Moreover, carbohydrates must be minimized because of its compatibility with water.
