Research progress of carbon fiber preparation at abroad
The analysis was made on the main raw materials of carbon fiber preparation,preparation methods,process steps,surface treatment of precursor fibers,preparation process and structure of carbon nanofiber,preparation of lignin-based carbon fiber,preparation of biomass-based activated carbon fiber,etc.,with emphasis on elaborating the general theory and representative research conclusions of fiber reinforcement and stabilization reaction.At the same time,the main global carbon fiber manufacturers,production capacity and product performance were introduced.Based on the foreign research status and research focus on carbon fiber preparation,the challenges in raw materials and wastes caused by the capacity expansion were analyzed briefly,and it was predicted that the preparation of lignin-based carbon fiber and the recycling of carbon fiber reinforced polymers would become the future research hotspots.The research on carbon fiber would also develop in a more microscopic direction.
