采用超临界正丙醇从环氧树脂/碳纤维复合材料中回收三种不同的PAN基碳纤维（Toray T600 S、T700 S和Tenax STS 563 1）。利用单纤维拉伸试验、SEM、XPS和微滴试验对回收碳纤维进行了表征。回收的碳纤维的拉伸强度和模量与相应的原样碳纤维非常相似。但表面氧浓度显著降低，导致与环氧树脂的界面剪切强度降低。(C)2008爱思唯尔有限公司保留所有权利。
Three different PAN based carbon fibres (Toray T600S, T700S and Tenax STS563 1) were recycled from epoxy resin/carbon fibre composites using supercritical n-propanol. The recycled carbon fibres were characterised using single fibre tensile tests, SEM, XPS and micro-droplet test. The tensile strength and Modulus of the recycled carbon fibre was very similar to the corresponding as-received carbon fibres. However, the surface oxygen concentration decreased significantly, which Caused a reduction of the interfacial shear strength with epoxy resin. (C) 2008 Elsevier Ltd. All rights reserved.
