Microwave radiation effects on carbon fibres interfacial performance

In this paper, microwave radiation, a fast and cost-effective industrial surface 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 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.
