Abstract:In this study, a flexible macromolecule‐grafted‐carbon nanotube (t‐CTN‐SPEEK) is developed and utilized as bridge to enhance the interfacial properties of high‐modulus carbon fiber (HM‐CF) reinforced poly (ether ether ketone) (PEEK) composites. With t‐CTN‐SPEEK sizing, the wettability of HM‐CF is enhanced, thereby promoting better resin wetting. The increased roughness induced by the t‐CTNs‐SPEEK on the surface of the HM‐CF affords improved mechanical interlocking among interface. Additionally, SPEEK enhances … Show more
