Abstract
A process for producing fiberglass reinforced molded articles of superior surface quality involves preparation of a mat of glass fiber comprised of a majority of fibers having a diameter of less than one micron and a minority of fibers having a diameter greater than one micron. A sizing is applied to the fibers. The sizing includes a coupling agent preselected to be compatible with the moldable material, e.g. nylon. The glass fiber mat is comminuted into pieces shaped and dimensioned for combination with the moldable material to form a composite having a range of to 50% of glass fiber by weight. The composite is then molded by a conventional process to yield a fiberglass reinforced article with superior surface quality.
