Research on the Mechanical and Thermal Properties of MWCNTs/CF Reinforced Epoxy Resin Matrix Composite Patch

The mechanical and thermal properties of multi-walled carbon nano-tubes and carbon fiber reinforced epoxy resin matrix composite patch were tested, which was prepared by the hand lay-up method. The results indicated that the imagination observed by SEM presented good resin-impregnation for both of the two kinds of composite patches, and the mechanical and thermal properties of composite patch could be effectively increased by improvement of the interface combination after adding MWCNTs. For the mechanical properties of composite patch reinforced with MWCNTs, the interlaminar shear strength, bend strength and impact-tolerance were separately increased by 3.1%, 51.66% and 60.7%; and heat-resistance obtained by DMA were shown better thermal stability.
