Grafted cnt onto cf surface
WebSep 1, 2016 · The bond strength of the CNTs grown on the CF surface ranged from 140−260 MPa, which is sufficiently high to withstand the mechanical force at the interface of CNT-grafted CF, e.g., fiber-reinforced composites. WebJun 26, 2024 · Surface enhancement of components is vital for achieving superior properties in a composite system. In this study, carbon nanotubes (CNTs) were grown on carbon fiber (CF) substrates to improve the surface area and, in turn, increase the adhesion between epoxy-resin and CFs. Nickel (Ni) was used as the catalyst in CNT growth, and …
