Constructing Ti3C2Tx/Carbon fiber hybrids for enhancing the interfacial strength and erosion wear resistance of EP-based composite coating

Composite coatings are indispensable for protecting the offshore steel materials serviced in splash zone. But mechanical properties of conventional epoxy resin (EP) poor, which would lead to a short-term lifespan. The carbon fiber (CF) with excellent is an ideal filler reinforce EP coating, thus we chemically grafted Ti3C2Tx nanosheets onto CF via dopamine enhance interface adhesion and compatibility between CFs EP, improve strength erosion wear resistance CF/Ti3C2Tx composite coating. flexural property CF/Ti3C2Tx@EP coating was evaluated by three-point bending test, its increased 26.97% compared pure tribological behaviors were tested using UMT-3 tribometer test rig. A rig used evaluate performances coatings. When contrasted CF/Ti3C2Tx@EP? rate lowered 79.39%, mass volume reduced, respectively, 21.31% 66.85%, this ascribed enhanced interfacial combination Ti3C2Tx/CF hybrids EP. We investigated failure behavior revealed strengthening mechanism evoke widespread interest developing high-performance long-term protective zone marine environment.
