Cross-linked polyethylene fibers as low-cost precursors for carbon fibers

The proposed research aims to develop a novel and cost-effective method for producing carbon fibers using silane-grafted polyethylene (PE) as an alternative precursor. This approach integrates silane grafting, melt-spinning, stabilization, and carbonization processes to enhance the thermal stability and cross-linking of PE, making it suitable for carbon fiber production. By leveraging silane chemistry, the project seeks to eliminate or significantly reduce the reliance on traditional stabilization techniques, such as sulfonation, which produce toxic byproducts. The expected benefits include lower production costs, improved environmental sustainability, and expanded applications for carbon fibers in industries such as aerospace, automotive, and construction. The collaboration between the University of Calgary and RWTH Aachen University will foster innovation in polymer processing and carbon fiber precursor development, strengthening Canada’s research capabilities and contributing to the global advancement of sustainable materials science?.
