王浩教授：碳纤复材如何实现高效回收利用？

Core Insights - The composite materials industry has become a significant sector in manufacturing, with carbon fiber composites widely used in aerospace, automotive, and wind power industries due to their excellent performance [1] - The production of carbon fiber is expensive and energy-intensive, leading to a substantial accumulation of thermosetting carbon fiber composite waste, which poses serious negative impacts on resources and the environment [1] - Effective recycling of carbon fiber into high-value resources is considered a crucial research direction for the future of carbon fiber and carbon fiber-reinforced green composites [1] Recycling Challenges - Current recycling methods for carbon fiber composites face several challenges: mechanical recycling is straightforward but results in significant loss of mechanical properties; chemical recycling methods, such as subcritical or supercritical solvent processes, have harsh reaction conditions and high costs; pyrolysis recycling processes are complex, with process parameters significantly affecting the performance of regenerated carbon fiber [1] - Professor Wang Hao from Swinburne University of Technology emphasizes four promising pathways for efficient recycling: high-temperature pyrolysis, mild condition solvent decomposition, epoxy vitrimers, and bio-based thermosetting resins [1] Professor Wang Hao's Contributions - Professor Wang Hao is a prominent figure in the field, having published over 500 papers and holding an H-index of 114, with a total citation count of 54,000 [2] - He notes that the energy required for carbon fiber recycling is less than 10% of that needed for production, with performance retention rates reaching 80-90% [2] - The recycling and utilization of carbon fiber composites are vital for resource conservation, waste reduction, and supporting industry innovation and sustainability commitments [2] Upcoming Forum - DT New Materials will invite Professor Wang Hao to participate in the 2025 Fourth Green Composite Materials Forum on November 30 in Hangzhou, where he will present a report on "Recycling and Reutilization of Carbon Fiber Composites" [2] - The forum, themed "Green Composites, Innovative Future," will focus on resins and fibers, composite technologies, and downstream applications, aiming to create a platform for industry-academia-research collaboration to promote technological breakthroughs and industrial integration in green composites [2]
