Abstract Different contents (mass fraction 0.25%, 0.50%, 1.0%) of carboxyl multi-walled carbon nanotubes (MWCNTs-COOH) were dispersed in 603 epoxy resin. T700 carbon fiber prepared containing carbon nanotubes had been successfully produced by hot-melt method and then the laminated composites plates were prepared. The results confirmed that with the increase of MWCNTs-COOH content, the cured degree of matrix is gradually decreased. When the MWCNTs-COOH content is less than 0.5%, MWCNTs-COOH can improve the mechanical properties of the resin matrix and carbon fiber composite material; and when MWCNTs-COOH content increased to 1.0%, the properties of the matrix and the composite material are degraded.
