Analysis of New Precursor Technologies for Low-cost Carbon Fibers
As a reinforcement of lightweight and high-strength advanced composite materials,carbon fiber has seen rapid development in usage in areas such as wind power,hydrogen storage cylinders,and automo-biles,in addition to traditional aerospace fields in recent years.The higher price of carbon fiber is the pain point for its further expansion of application,and the low-cost of carbon fiber is increasingly attracting attention.This article reviews the new types of precursor fibers used in low-cost research and development of carbon fibers in recent years,such as lignin,polyolefin,textile grade PAN and other precursor fiber.The performance,advantages,dis-advantages,and cost situation of carbon fibers produced by new filament technologies are discussed.It summarizes the new technologies used in low-cost carbon fibers,and looks forward to the urgent problems and future develop-ment trends in the low-cost development of carbon fibers.
