The term, GFRP, stands for glass fiber reinforced polymer. It is what is known as a composite material, consisting as it does of a matrix of polymer that has been reinforced with fibers to give it strength. GFRP composite is used in many industries, including marine, automotive, construction, ballistic armor and aerospace.
Other types fiber reinforced polymer exist, mainly and consist mainly of carbon, basalt, or aramid. Aramid is a strong and heat-resistant synthetic fiber. Rarely, other materials are used such as wood, asbestos, or paper. The polymer part of an FRP is usually a vinylester, epoxy, or a polyester thermosetting plastic. The term thermosetting refers to the property of plastic where it is a liquid or soft plastic at low temperatures but hardens irreversibly when exposed to high termperatures.
GFRP materials are used where light weight and strength are necessary, as in the aerospace industry. The Aloha Airlines incident that occurred in April of 1988 is an example where a material failed. A flight attendant was killed when she was swept overboard by an explosive decompression that tore a section off roof of the plane on the short hop between Hilo, Hawaii, and Honolulu. The incident caused injury to 65 passengers and crew.
At sea, GFRPs were mostly confined to recreational water craft. It was not until three decades later that larger boats started to incorporate the material. They are particularly useful in this industry because they may be crafted into sometimes complicated configurations. They are lightweight, cheap, resistant to both impact and corrosion, and are vibration-damping.
Because of the same properties that make it favorable for marine use, GFRP is useful in the manufacture of high-performance automobiles. Incorporated into fiberglass trucks, its light weight means that a bigger payload may be transported. Fiberglass is also preferable to steel in a car crash. Fiberglass will contain the vibrations to a localized area, while steel will transfer the vibration, and hence the shock, throughout the vehicle.
Ballistic armor, with a substantial content of GFRP, has a number of different uses in civilian as well as military sectors. Not only does it protect assets such as vehicles and buildings, it is also used to protect people. Unlike other materials, like steel armor, fiberglass may be re-engineered in the field using simple power tools that area readily available.
GFRB ballistic armor can sometimes protect rooms like courtrooms from the tendency of bullets to richocet. It is not unknown for a disgruntled hot head to shoot up the courthouse. This happens regularly on courtroom dramas like Medium, CSI and Law and Order, for example. It also happens in real life, as an incident in Tyler, Texas in 2005 shows.
One of the best-known uses for reinforced polymers is in bullet-proof vests, generally in law enforcement and the military. A ballistic vest saved the life of Kate Todd, only to have her shot in the head by a sniper moments later. There have been several television episodes featuring cowboy vendors who sell defective armor to soldiers.
