摘要
Because of the inert surface and low wettability of carbon fibers (CF), the interfacial binding between CF and polyetheretherketone (PEEK) matrix is poor. The surface of CF was modified by preparing sulfonated polyetheretherketone (SPEEK)/carboxylated carbon nanotubes (MWCNTS) sizing agent, which contributed to the developed physical and chemical compatibility of reinforcing fibers and the matrix. After sizing by the sulfonated polyether ether ketone with a sulfonation degree of 16.67% and 0.5wt% carboxylated carbon nanotubes, the flexural strength and interlaminar shear strength of the modified composites were significantly improved by 74.2% and 84.2% by comparison to CF/PEEK composites without sizing agent. The coating method by SPEEK-MWCNTS is confirmed to be an essential approach to constructing excellent interface between the enhancement phase and thermoplastic matrix.
