This article is about the plastic composite. For insulation material, see glass wool.

Fiberglass American English or fibreglass Commonwealth English is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix —most often based on thermosetting polymers such as epoxy , polyester resin , or vinyl ester resin —or a thermoplastic. Cheaper and more flexible than carbon fiber , it is stronger than many metals by weight, non- magnetic , non- conductive , transparent to electromagnetic radiation , can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools , hot tubs , septic tanks , water tanks , roofing, pipes, cladding, orthopedic casts , surfboards , and external door skins. Because glass fiber itself is sometimes referred to as "fiberglass", the composite is also called fiberglass-reinforced plastic FRP. This article will adopt the convention that "fiberglass" refers to the complete fiber-reinforced composite material, rather than only to the glass fiber within it.

Carbon-fiber-reinforced polymers are a similar composite material in which the reinforcement are carbon fibers. Glass fibers have been produced for centuries, but the earliest patent was awarded to the Prussian inventor Hermann Hammesfahr — in the U. Mass production of glass strands was accidentally discovered in when Games Slayter , a researcher at Owens-Illinois , directed a jet of compressed air at a stream of molten glass and produced fibers. A patent for this method of producing glass wool was first applied for in Originally, Fiberglas was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.

Evidence for these classifications is primarily from studies on experimental animals and mechanisms of carcinogenesis.

Fiberglass also called fibreglass and glass fibre is material made from extremely fine fibers of glass. Fibreglass is cheaper and more flexible than carbon fibre. It is stronger than many metals when compared by weight , and can be moulded into complex shapes. The plastic matrix is usually a thermoset polymer — such as epoxy or polyester resin, or it may be a thermoplastic. It is used as a reinforcing material for many polymer products. The composite material , that is produced by this method is called "fiberglass" in popular usage.

Fiberfab was an American automotive manufacturer established in Starting with accessories and body parts, they progressed to making kit cars and fully assembled automobiles. They became one of the longest lasting kit car manufacturers. SCE also manufactured custom chassis. Noel Johnson was a Fiberfab employee who later became part owner of the company. In Fiberfab was made a subsidiary of Velocidad Inc. The company was also referred to as Fiberfab-Velocidad Inc. The Fiberfab company moved from Palo Alto to Sunnyvale. He died of a heart attack while serving his sentence on 26 December

For a great history of the Fenwick rod company, see Vic Johnson's book of the same title General Reference 2. If you collect Fenwick rods, you gotta have Vic's book. It covers not only Fenwick history and company ownership, but materials development, fly rods, bass rods, spin rods, and the rest of the product lines. This Wiki page is not intended as a replacement for the book. Instead, this page is more of a supplement. The Fenwick book doesn't contain a comprehensive list of model numbers, nor does it discuss the casting qualities of the fly rods.

Therefore if a collection of fibers can be arranged permanently in a preferred direction within a material, and if the fibers can be prevented from buckling in compression, then that material will become preferentially strong in that direction. Good Old Boat. In certain concentrations may even occur a Air flow test for the extraction and potentially explosive mixture. Fiber [edit] Unlike glass fibers used for insulation, for the final structure to be strong, the fiber's surfaces must be almost entirely free of defects, as this permits the fibers to reach gigapascal tensile strengths. Woodhead Publishing. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of fiberglass was only made possible with the invention of finer machine tooling. Its first main civilian application was for the building of boats and sports car bodies, where it gained acceptance in the s. Steel Bar x4. Its use has broadened to the automotive and sport equipment sectors as well as aircraft, although its use there is now partly being taken over by carbon fiber which weighs less per given volume and is stronger both by volume and by weight. Getting Started. N" PDF.

Fiber-reinforced concrete or fibre-reinforced concrete FRC is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented.

It is usual to introduce impurities into the glass in the form of other materials to lower its working temperature. They are then typically heat-treated and cut to length. The material must conform to the mold, and air must not be trapped between the fiberglass and the mold. The first commercial production of fiberglass was in References 1. In its pure form it exists as a polymer , SiO 2 n. This reduced the insulation properties to values typical of the plastic, but now for the first time, the composite showed great strength and promise as a structural and building material. Its use has broadened to the automotive and sport equipment sectors as well as aircraft, although its use there is now partly being taken over by carbon fiber which weighs less per given volume and is stronger both by volume and by weight. AR-glass is alkali-resistant glass. Cheaper and more flexible than carbon fiber , it is stronger than many metals by weight, non- magnetic , non- conductive , transparent to electromagnetic radiation , can be molded into complex shapes, and is chemically inert under many circumstances.
