微波辐照对碳纤维界面性能的影响

摘要：微波辐照作为一种快速、高效、无需化学试剂的工业化处理手段，被用来对 T300 碳

生的极化电流对碳纤维的形貌、成分与结构造成影响。短时间微波辐照可以提升纤维与树脂10

pretreatment method without chemicals, was employed to pretreat T300 carbon fibres and improve

the carbon fibres /matrix interfacial properties. The microwave pretreatment mechanism on carbon

fibres was studied in an experiment divided microwave treated carbon fibres into a microwave

radiation section and a pure current section. The polarization current in the carbon fibre induced

by microwave radiation helped microwave effects interact on the morphology, compositions, and 25

structure of carbon fibres. Carbon fibres pretreated with short time microwave radiation had an

increased thermodynamic work of adhesion and the interfacial shear strength, indicating

microwave radiation pretreatment of carbon fibre promises to be an effective method of fiber

treatment.
