摘要
Abstract
The single-walled carbon nanotubes(SWCNTs)were non-covalently modified and combined with epoxy resin(EP)to prepare SWCNTs/EP composites.The nanomodified epoxy resin was then compounded with carbon fiber(CF)to fabricate CF/SWCNTs/EP multiscale composites,with subsequent investigation of their structure and properties.Results demonstrate that non-covalent modification improved the dispersion of SWCNTs in the EP matrix.When the mass fraction of SWCNTs reached 0.005%,the composite exhibited significant enhancements.The flexural strength and modulus increased by 29.2%and 46.1%respectively,the impact strength improved by 47.9%,and the tensile strength rose by 58.9%.Scanning Electron Microscopy(SEM)analysis revealed the bridging reinforcement mechanism of SWCNTs within the matrix.The thermal properties of EP were also enhanced through SWCNTs incorporation.Using the solution impregnation method,CF/SWCNTs/EP multiscale composite laminates showed 22.5%and 32.8%improvements in flexural strength and modulus respectively at 0.005%SWCNTs loading,along with 15.2%enhancement in interlaminar shear strength and improved interfacial bonding between matrix and fibers.Carbon fiber pressure vessels fabricated via wet winding process demonstrated that the CF/SWCNTs/EP modified vessels achieved approximately 15.5%higher burst pressure compared to conventional CF/EP vessels.关键词
