Carbon fibre composite rigid felts (long and short)

Vulcan now has advanced carbon fiber felt technology, with carbon fiber soft felt as raw material to produce cured felt and after 2400 ℃ high-temperature graphitization of one-time molding. The hard felts are structured by density gradient method and treated with surface treatment or purification for higher strength and better oxidation resistance. All felting equipment, impregnation equipment, curing and molding equipment, carbonization and graphitization equipment, and high temperature chemical purification equipment are developed independently.
