Introduction to melt-blown/ nano fiber/ carbon fiber technologies

Carbon fiber technology

Introduction to carbon fiber technology

Carbon fibers and activated carbon fibers are manufactured using spinning, low and high-temperature treatment technologies.
Our system is designed and provided based on our experience in which we manufactured carbon fibers and activated carbon fibers using pitch-based materials.
