The development of FRP

Feb 21, 2019

FRP fiber reinforced plastic is based on synthetic resin, glass fiber and its products (glass cloth, glass ribbon, glass)

A felt made of a felt, etc. as a reinforcing material. It is solid in texture, high in strength and hardness, and can be compared with steel, so it is also called glass fiber reinforced plastic.

FRP concentrates the advantages of glass fiber and synthetic resin and is superior to the original material properties. The material properties can be expressed as 1+1>2. FRP has many advantages: small specific gravity, only 1/4 to 1/5 of steel; high specific strength, more than many existing materials; good corrosion resistance, good for mediums such as acid, alkali, humid climate, fresh water and seawater Corrosion resistance; good weathering resistance, low water absorption; smooth surface of the product, can reduce resistance; good anti-magnetic, sound insulation, electrical insulation properties, low thermal conductivity, no reflection of radar waves; good impact resistance, after collision It can recover quickly and is not easy to destroy.

In 1964, the US Navy built the first FRP dinghy. Since then, countries around the world have begun to develop FRP ships. In China, FRP fishing vessels are one of the key development of FRP vessels, but with the improvement of people's living standards and the further development of FRP industry, FRP yachts will be another development focus of FRP vessels.

At present, there are more than 2 million FRP ships in the world, including dozens of air-cushion boats, deep-water survey vessels, fishing boats, patrol boats, military speedboats, yachts, minesweepers and submarine components.
