History Glass-Fibers

Fiberglass is the original fiber reinforcement of modern composites. Though the ancient Phoenicians, Egyptians and Greeks knew how to melt glass and stretch it into thin fibers, it wasn’t until the 1930s that the process evolved into commercial-scale manufacturing of continuous fibers, which would later be used as structural reinforcements. Patent applications filed between 1933 and 1937 by Games Slayter, John Thomas and Dale Kleist, employees of Owens-Illinois Glass Co. (Toledo, Ohio), record the key developments that step-changed the industry from producing discontinuous-fiber glass wool to making continuous glass filaments with diameters as small as 4 microns (4 millionths of a meter) and thousands of feet long. Ensuing breakthroughs made the process commercially viable and cost-competitive.


The last two patents in the series, entitled “Textile Material” and “Glass Fabric,” foreshadowed the future of glass fiber as a textile reinforcement. The patents were awarded in 1938, the same year that Owens-Illinois and Corning Glass Works (Corning, N.Y.) joined to form Owens-Corning Fiberglas Corp. (OCF).


The new company marketed its glass fiber under the trade name Fiberglas, which was the genesis of the common generic reference to fiberglass. It was not long before a number of other manufacturers entered the market and, through numerous process and product innovations, contributed to a worldwide structural composite reinforcements market of roughly 4 to 5 million tons per year.
