Sigmatex (Runcorn, UK) has developed a new carbon fiber composite material within its sigma RF product range. Primarily aimed at the automotive industry, it is a blend of polypropylene fibers (55%) and carbon fiber (45%). Sigmatex says 85% of the fibers are aligned, which the company says provides superior mechanical properties when compared to other recycled materials. Sigmatex also has developed a polyamide version of the material. Sigmatex reports that sigma RF enables the complete manufacture of a noncrimp fabric by reformatting surplus virgin carbon fiber. Targeted applications and end markets include automotive, sports, leisure and energy.
