| 제목 | Mechanical strength enhancement of carbon fibers by hybrid surface treatments |
| 초록 | In this study, surface defects and surface layer etching of CF were attempted by using electrochemical oxidation method and surface oxidation treatment was performed. Also, the microstructure was strengthened by the electron beam method and the change of the mechanical strength (tensile properties, interfacial shear strength) was investigated. Depending on the hybrid surface treatment of the carbon fibers, the diameter of the fibers decreased from the initial 7 μm to 6.5 μm. The hybrid surface treatment of carbon fiber, which has a structure similar to onion skin, causes repetitive changes in the crystal structure due to the repetitive pattern of oxidation (1st amorphous oxidation, 2nd disordered graphitic structure oxidation) and also reduces the diameter of the carbon fibers. The development of hybrid surface treatments is expected to gradually increase the tensile strength of carbon fibers by more than 50%. |
