Influence of Excilamp Treatment on Characteristics of Carbon Fibers

Abstract:

To activate the surface of carbon fiber for better reinforced composites, the Xe₂^* excilamp was applied. The scanning electron microscopy (SEM) showed that the surface of Xe₂^* excilamp-treated carbon fibers was rougher than that of the control. X-ray photoelectron spectroscopy (XPS) analysis indicated that the Excilamp-treated fibers possessed more polar functional groups than the control fibers. After 2 min of irradiation, the wetting rate of treated carbon fibers in epoxy resin in balance increased by about 150% compared with the control, and the short-beam strength of carbon fiber/epoxy composites increased 6.6%.
