Harper International (Buffalo, N.Y., USA), a manufacturer of thermal processing solutions for advanced materials, reported on June 28 that it has booked another contract for a fully integrated pilot scale carbon fiber conversion line. The line will be installed in Europe to produce carbon fiber for use in advanced communication technology. The name of the customer was not revealed.
The fully integrated line incorporates several progressive design features for the production of carbon fiber from 6k polyacrylonitrile (PAN) precursor and is engineered for higher than traditional processing speeds. Harper will supply its advanced oxidation oven technology, LT and HT slot furnaces rated for 1,000°C/1,832°F and 1,600°C/2,912°F respectively, fiber surface treatment and size application conditioning, waste gas abatement and material transport systems.
“We are pleased to add this project to our list of Harper-designed, technically advanced complete carbon fiber lines,” says Charles Miller, Jr., president, Harper International."
