| Abstract Scope |
Scalable carbon nanotube (CNT) yarns and sheets were treated with oxygen plasma to improve their interface shear strength (IFSS) with aerospace resins for potential engineering applications. Two batches of CNT yarns with different linear densities and concentrations of CNTs were evaluated. The plasma treatment was varied by controlling power up to 100 W and exposure time from 30, 45, and 60 minutes. Unlike some other surface functionalization treatments, an increase of 39.5% in IFSS was achieved without reducing the tensile properties of the CNT yarns. Raman spectroscopy showed an increase in the ID/IG band ratio due to the plasma treatment. Specimens were further examined with Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) to determine if this increase was due to the addition of functional groups. Plasma treated CNT yarns were fabricated into [0/90]s laminates with CYCOM 5250-4 bismaleimide resin and compared with untreated laminates to determine if plasma treatment confers an increase in mechanical properties at the macro scale. |
