| Abstract: | The main objective of this paper is to develop a high-wear-resistant short-carbon-fiber-reinforced polyetheretherketone (PEEK)
composite by introducing additional multiwall carbon nanotubes (MWCNTs) into it. The compounds were mixed in a Haake batch
mixer and fabricated into sheets by compression molding. Samples with different aspect ratios and concentrations of fillers
were tested for wear resistance. The worn surfaces of the samples were examined by using a scanning electron microscope (SEM),
and the photomicrographs revealed a higher wear resistance of the samples containing the additional carbon nanotubes. Also,
a better interfacial adhesion between the short carbon fibers and vinyl ester in the composite was observed. |
