Abstract

The invention provides a device used for carbon fiber surface modification. The device comprises twin-stage epoxy resin bath devices, an oxidation treatment device, a carbon fiber surface washing device and a drying device which are connected in sequence, wherein a carbon fiber surface scrubbing device is arranged between the twin-stage epoxy resin bath devices; the oxidation treatment device is a high-temperature reaction kettle; an epoxy resin bath device is arranged between the carbon fiber surface washing device and the drying device; the drying device is an electric heating baking oven. The problems that the final composite material performances of carbon fibers are reduced as the strength of the carbon fibers is lost while the surface performances of the carbon fibers are improved in existing carbon fiber surface modification methods are solved by adopting the device.

Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a device for modifying the surface of carbon fibers. Background technique [0002] Carbon fiber is a material that has both structural load-bearing and functional properties. In recent years, it has been widely used in aerospace, automobile, transportation, construction, chemical industry and other fields. The untreated carbon fiber has few surface active groups, high surface inertness, poor interfacial binding ability when composited with the matrix, and many interfacial defects. These problems greatly limit the advantages of carbon fiber, such as high strength and high specific modulus. Therefore, treating the surface of carbon fiber is the key to promoting the development of carbon fiber use. At present, there are many researches on carbon fiber treatment methods, mainly focusing on treating the surface of carbon fiber to make the surface have active groups or im...
