Glass-reinforced plastic ('''GRP'''), is a Composite Material or Fibre Reinforced Plastic made of a Plastic reinforced by fine Fiber s made of Glass . Like Graphite-reinforced Plastic , the composite material is commonly referred to by the name of its reinforcing fibers ( Fiberglass ), an example of part-for-whole Metonymy . The plastic is most often Polyester or Vinylester , but other plastics, like Epoxy (GRE), are also sometimes used. The glass is mostly in the form of Chopped Strand Mat (CSM), but woven fabrics are also used. GRP/GRE is a versatile material with many uses. Although GRP was originally developed in the UK during the Second World War as a replacement for the molded plywood used in aircraft Radome s (GRP being Transparent to Microwaves ) its first main civilian application was for building of Boat s, where it gained acceptance in the 1950s , and now plays a dominant role. But its use has broadened over the years, and it is used extensively within the automotive and sport equipment sectors, although its use there is being taken over by Carbon Fiber because of its lower weight. GRE is also used to make Hot Tub s, pipes for drinking water, sewers, chemicals, and so on. Advanced manufacturing techniques such as pre-pregs and fibre rovings extend the applications and the tensile strength possible with fibre-reinforced plastics. GRP is also widely used in the Telecommunications industry for Shroud ing the visual appearance of Antennas , due to its RF permeability and low signal Attenuation properties. It may also be used to shroud the visual appearance of other equipment where no signal permeability is required, such as equipment cabinets and Steel support structures, due to the ease with which it can be moulded, manufactured, and painted to custom designs, to blend in with existing structures or brickwork.
