Fiberglass is highly appreciated for its lightweight, natural toughness, ability to withstand harsh weather, and the variety of surface textures it offers.
Research History of Glass Fiber
The Beginning of Research on Fiberglass
Research into the widely used fiber-reinforced plastics began in the 1930s and attracted the attention of industries such as the aerospace industry. The turning point came in 1932, when a researcher at the University of Illinois at Owens stumbled upon a way to mass-produce glass strands. This is accomplished by introducing a stream of compressed air into the molten glass, forming fibers.
Developments in Glass Fiber Research
In 1935, when Owens merged with Corning Corporation, patented “fiberglass” was born, using a method pioneered by Owens-Illinois.
By 1936, DuPont created a resin that could be successfully combined with “fiberglass” to produce plastic.
The first precursor to the modern polyester resins we use today was created by Cyanamid in 1942, using a peroxide curing system in its creation.
Fiberglass History During World War II
During World War II, fiberglass became the preferred alternative to molded plywood for making aircraft radomes because of its microwave permeability. Its main non-military use began in the 1950s, when it was used to build boats and sports car bodies. Today, its use has expanded to the automotive and sports equipment industries. For some products, such as aircraft, fiberglass has been replaced by carbon fiber, which is stronger per unit volume and weight.
How to Make Fiber Glass
Advanced manufacturing methods such as prepregs and fiber rovings have expanded the application range of fiberglass and significantly increased the tensile strength achievable for fiber-reinforced plastics.
Industries Where Fiberglass is Used
Fiberglass has gained acceptance in the telecommunications industry as shielded antennas due to its RF penetration and minimal signal attenuation. It can also be used where signal permeability is not required, such as covering other equipment, as it can be easily molded and painted to blend with existing structures and surfaces. Some power industry products often contain sheet electrical insulators and structural components made of fiberglass. Due to its lightweight and durability, fiberglass is commonly used in protective gear such as helmets and is widely used in many sports, including goalie and catcher masks.
