Abstract
A process using ultraviolet light having a wavelength of 160 to 500 nanometers without higher wavelengths and a high intensity between about 1 and 40 watts/cm to surface treat a carbon containing fiber is described. The treated fiber contains an enhanced amount of oxygen on the surface which significantly improves the bondability of the fiber in composites.
