Coaxial Layered Fiber Spinning for Wind Turbine Blade Recycling
Background Plastic waste presents an acute environmental challenge to nearly all freshwater and marine ecosystems. The long degradation time of plastic requires effective methods of disposal to avoid adding additional plastic waste to aquatic environments. The end-of-life waste from wind turbine blades (WTBs) is also a pressing issue, as WTB waste...

Multifunctional Carbon Fibers with Aligned Graphitic Layers
­Carbon fibers can be made from carbonized precursors, e.g., cellulose, lignin, pitch, polyacrylonitrile (PAN), or Kevlar. Compared to pitch, PAN has advantages of controlled molecular weights from chemical synthesis, easy processability, reduced viscosity, and controlled crystallinity and molecular alignment that can benefit the efficiency of...
