Glass fiber reinforced plastic(FRP)is also called GFRP,that is,fiber reinforced plastic,generally refers to the use of glass fiber reinforced unsaturated polyester,epoxy resin and phenolic resin matrix.Reinforced plastics with glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics,or glass steel,which is different from tempered glass.

　　FRP is a composite material that has developed rapidly in the past fifty years.70%of the output of glass fiber is used to make FRP.FRP has high hardness and is much lighter than steel.It can be used as fuel tank and pipe on jet aircraft to reduce the weight of the aircraft.The miniature oxygen cylinders carried by the astronauts on the moon are also made of fiberglass.

　　Glass steel is easy to process,not rusty and not rotten,and no paint is needed.my country has widely adopted FRP to manufacture various small motorboats,lifeboats,yachts,and automobile manufacturing,saving a lot of steel.Since FRP is a kind of composite material,its performance adaptability is very wide,so its market development prospect is very broad.

　　After more than 40 years of development,my country's FRP industry has also achieved successful applications in various fields of the national economy,and has played an important role in economic construction.
