Abstract
The density of hydroxyl groups present on the surface of glass, such as E-glass fibers, is increased by subjecting the surface to a radio frequency induced gas plasma containing water vapor. Surfaces so treated exhibit enhanced adsorption of hydrolyzed organo silane coupling agents applied to improve adhesion between glass fibers and resin matrices in the manufacture of reinforced composites.
