A process of improving resistance to conductive anodic filament (CAF) formation is disclosed. The process includes dissolving a base resin material, a lubricant material, and a coupling agent in a solvent to form a functionalized sizing agent solution. The process also includes applying the functionalized sizing agent solution to individual glass fibers following a glass fiber formation process. The process further includes removing the solvent via a thermal process that partially converts the base resin material. The thermal process results in formation of coated glass fibers having a flowable resin coating that is compatible with a pre-impregnated (prepreg) matrix material utilized to form a prepreg material for manufacturing a printed circuit board. During one or more printed circuit board manufacturing operations, the flowable resin coating flows to fill voids between the individual glass fibers that represent CAF formation pathways.
