Carbon fibers are known for their high stiffness, high strength, and low density and are used as a reinforcement in structural composites for applications such as wind turbine blades, and tennis rackets. The goal of this work is to develop a robust process for manufacturing high quality and low cost carbon fibers from lignin-based polymer blends. To obtain the optimum combination of spinnability and thermal properties, high molecular weight lignin is blended and melt processed with different polymers and the impact of blending on the properties of the fibers is characterized using advanced thermal analysis.
