*also offer unusual possibilities in decorative fabrics. Here the glass fibers would be employed both for design effects and to give added dimensional stability to the fabrics. Research in such combinations is still in its initial stages.


The first commercial use of Fiberglas fibers was for air filtration. During the pre-war years, pads of relatively coarse fibers, treated with an adhesive, were employed to strain dust and pollen from the air circulated by forced-warm-air heating systems, and air conditioning systems. Today, Fiberglas air filters are standard requirements for many of these systems in factories, stores, theatres and other buildings.


The thin, felted Fiberglas mats which, by holding the power-producing material

in place, gave longer life to storage batteries in military automotive equipment during the war, were used for the same purpose in passenger cars, buses and trucks before the war, and are again being widely used in storage batteries for peace-time automotive equipment.

In addition, new uses for the mat have been developed. In roll form, it is being employed as a material for wrapping underground oil, gas and other pipe lines to protect them against corrosion and electrolytic action. The material can be wrapped around bitumen or coal-tarcoated pipe, thus forming a continuous water-tight bond. ,

Primarily because of the high tensile strength and non-moisture-absorption characteristics of the individual glass fibers, the Fiberglas mats are being employed as the base for a new plastic laminated material for plastic coil forms, condenser spacers, stand-off insulators, etc., in radio, radar, television and other high-frequency electronic devices.

BESIDES FOR AIR FILTERS, with which theatre men are familiar, Fiberglas is also used for tower packing. Here is seen the material being packed into an alcohol distillation column. By using this product of the OwensCorning Fiberglas Corporation, towers have been built which will convert high viines into 191.5 proof alcohol in approximately half the time formerly required. A similar use of Fiberglas is found in the oil industry.



'Fiberglas mat is also being employed as a base material for gaskets and sheet packing.


Fiberglas was born of industrial research. From the time of its birth, research has been depended upon to make it possible to produce finer and stronger fibers, to develop new uses for Fiberglas materials, to adapt the materials to meet needs that cannot be adequately met by other materials, and, finally, to produce progressively better materials that can be sold at progressively lower prices.

For a great many years people have known how to make good glassebut not glass of a kind that can be produced in the form of strong, durable and almost infinitely fine fibers. To mention only one factor, expansion of surface area presented a problem that only. skilled and patient research could solve.

Because glass does not rust, and is able to withstand surface attacks of many acids and mild alkalies without any apparent harm, most people assume that, aside from breakage, glass is practically indestructible. But the glass chemist knows that some glasses are more durable than others, and that surface attacks do have an effect on most commercial grades of glass. The greater the surface area, the greater is the opportunity for these attacks to occur.

When a given mass of glass is drawn into fine fibers its surface area is increased many times. For this and other reasons it is necessary to develop special glass formulas as one step towards providing the fine glass fibers with resistance to weathering, chemical action, and other infiuences to which they will be exposed. No single formula will solve the problem, since the properties the fibers must possess differ with the uses in which they will be employed.

Fiberglas research is not confined to the companyis own laboratories. Many problems involved in the development and testing of materials are regularly referred to independent testing and university laboratories in order to bring fresh viewpoints to bear. The laboratories of other manufacturers, too, have done a superb job in adapting Fiberglas materials to their particular needs, thus constantly broadening their fields of use.

New uses of Fiberglas have been found every year since glass in fiber form was first produced in this country on a commercial scale. Today Fiberglas is produced in more than 4,000 forms to meet the requirements of hundreds of different applications. There remains, however, plenty of new territory to be

explored. The war shelved more than 300 research projects covering potential

peace-time uses. These could not be completed because of the demands made by the war upon the Fiberglas research organization. This dammed-up flood of research has now been released. The entire resources of the Fiberglas research laboratories and pilot plants#the personnel of which constitutes approximately 10 per cent of all Fiberglas personneleis now focused upon the development of new processes, products, and markets.
