Abrasive Wear Behavior of CNT-Filled Unidirectional Kenaf–Epoxy Composites

Kenaf (Hibiscus Cannabinus) fibers have received significant attention for replacing the usage of synthetic fibers, especially glass fiber, in fabrication fiber-reinforced polymer (FRP) composites. The aim this research was to study change wear behavior kenaf-epoxy fiber composites by filling them with multiwall carbon nanotubes (MWCNT). In particular, effect untreated MWCNT (PMWCNT), acid-treated (AMWCNT), and silane-treated (SMWCNT) studied, using three different loadings, i.e., 0.5, 0.75, 1 wt.%. abrasive test conducted measure properties A thermal infrared camera also used punctual contact temperature during test, while abraded surfaces were analyzed stereomicroscope. Starting from considerable reduction rate introduction kenaf it observed that PMWCNT provided some further, yet modest, only at higher loadings. contrast, inclusion AMWCNT proved increase specific epoxy-kenaf composites, an worsened This may be due weakened interfacial bonding between epoxy. On other hand, presence SMWCNT improved CNT epoxy, as shown temperature. However, strength stipulated caused rougher worn debris, thus inducing a three-body effect.
