Abstract

The results of studies on the recovery of carbon fibers by the method of low-temperature solvolysis from prepreg and reinforced plastics based on it are reported. The surface of carbon fibers extracted from prepreg and carbon fiber reinforced plastics (CFRPs) was characterized using scanning electron microscopy, thermal analysis, Fourier transform infrared spectroscopy, and Raman spectroscopy to understand their thermal stability characteristics, possible surface chemical composition, and the presence of functional groups. It was shown that in the case of solvolysis of a single-layer carbon fiber, the recoverable carbon fibers contain a smaller amount of undecomposed polymer matrix than in the case of prepreg solvolysis.

低温溶剂分解在增强碳塑料加工中的应用

摘要

报道了基于低温溶剂分解法从预浸料和增强塑料中回收碳纤维的研究结果。使用扫描电子显微镜，热分析，傅立叶变换红外光谱和拉曼光谱对从预浸料和碳纤维增强塑料（CFRP）中提取的碳纤维的表面进行表征，以了解其热稳定性特征，可能的表面化学组成以及存在的功能组。已经表明，在溶剂分解单层碳纤维的情况下，与在预浸料坯溶剂化的情况下相比，可回收的碳纤维包含较少量的未分解的聚合物基质。
