What Is Glass Reinforced Plastic Used For?

 

What Is Glass Reinforced Plastic Used For

The use of glass-reinforced plastic—can be traced back to the Second World War. As a new technology at the time, glass and resin production volumes were quite low, and being a composite, its engineering characteristics were not properly understood.

However, compared to other materials, its benefits, for specific uses were quite apparent. Initial applications of glass-reinforced plastic were in protecting radar equipment, and it was used in ducting, for instance, airplane engine nacelles.

Modern Uses of Glass Reinforced Plastic

Every year, close to two million tons of unsaturated polyester resin are produced globally, and its ever increasing use is determined by a number of features, apart from being affordable:

  • Durability
  • High flexing tolerance
  • Low technology fabrication
  • Impact resistance
  • Corrosion resistance
  • Non-conductive to heat and electricity

Aviation and Aerospace

Glass reinforced plastic is extensively used in aerospace and aviation, though it is not utilized in the construction of the primary frame, as there are materials that are better suited for this application.

Typical applications of the component include in luggage racks, bulkheads, ducting, storage bins and in engine cowlings.

Railway Environments
Due to GRP not conducting electricity it is an ideal solution to be used in areas where there are high electrical currents such as railways/underground rail systems. GRP is fast becoming the preferred solution for our customers that operate in these environments.

Automotive Industry

For car fanatics, the 1953 Chevrolet Corvette was the first production car that had a fibreglass body. As a body material, glass reinforced plastic is yet to succeed against metal when it comes to large production volumes.

However, it has a huge presence in custom and auto kit markets, as well as in replacement body parts. The tooling costs are very low as compared to metal press assemblies and are suitable for smaller markets.

Boats and Marine

Fibreglass has reigned supreme in this industry for many years. It has properties that are suitable for boat building.

Although there were problems with water absorption in the early days, the modern resin is more resilient and as a result, composites have continued to dominate the marine industry for very many years.

Electronics

Glass reinforced plastic is used in the manufacture of circuit boards. Fibreglass is said to hold the electronic world together given that it is used in all electronics from radios, computers, TVs and even cell phones.

In Residences

Almost all residences have glass-reinforced plastic somewhere—whether in a shower tray or bathtub. Its other applications include spa tubs and furniture

Leisure

Many leisure products are made using fibreglass. For instance, how much glass-reinforced plastic do you think is present in Disneyland? The towers, the castles, and even the cars on the rides are mainly made from fibreglass.

Medical

Because of the low porosity of fibreglass, it’s hard wearing, and non-staining finish, it is suitable for use in medical applications such as X-ray beds as well as instrument enclosures.

Access ways

GRP is now becoming a very popular material for roof edge protection, handrails and other safety solutions due to its lightweight strength and affordable pricing.
