Abstract

The urgent requirement for efficient recycling strategies in the wind energy industry prompted this study to explore the behavior of methanesulfonic acid (MSA) in the solvolysis of carbon fiber-reinforced plastics (CFRP), as an alternative to standard solvents and acids. For the investigation, two layers of carbon fibers, infused with amine-based epoxy through a vacuum-assisted resin infusion process, were applied. The results showed that MSA was the most effective solvent for the solvolysis of CFRP, compared to other investigated common acids. The recycled products demonstrated satisfactory properties for both the matrix and fiber, which were comparable to those of the virgin materials.

通过非氧化性甲磺酸溶解回收环氧基碳纤维增强塑料
风能行业对高效回收策略的迫切需求促使本研究探索甲磺酸(MSA)在碳纤维增强塑料(CFRP)溶解过程中的行为,以替代标准溶剂和酸。在研究中,使用了两层碳纤维,通过真空辅助树脂灌注工艺注入胺基环氧树脂。结果表明,与其他调查过的普通酸相比,MSA 是溶解 CFRP 的最有效溶剂。回收产品的基体和纤维均表现出令人满意的性能,与原始材料的性能相当。
