Improving Interfacial and Reinforcing Properties of Plasma-Treated CNT-Phenolic Nanocomposites by Wettability and Acoustic Emission |
초록 |
carbon nanotubes (CNT) was treated by atmospheric pressure plasma treatment to modify reinforcing effects and interfacial adhesion in CNT-phenolic composites. A significant enhancement in the wettability of CNT was confirmed by static contact angle measurement. The advancing contact angle indicated a change in the surface from hydrophobicity to hydrophilicity. The interfacial adhesion between the carbon fibers and the plasma treated CNT-phenolic composites was improved, as evidenced by an increase in the apparent modulus. Due to the brittle nature of the phenolic matrix, dual matrix composites (DMC) were used in a modified fragmentation test. The different micro-failure modes were investigated by acoustic emission (AE) and electrical resistance measurements.
