The Great Development Road Of FRP Boats

Jul 27, 2020

Fiber reinforced plastics is fiber reinforced plastics (FRP, abbreviated as FRP). Nowadays, most of the ships on the market are FRP boats, and their materials are mainly FRP materials. What about the current development of FRP boats?

A ship whose hull is made of glass fiber reinforced plastic. The displacement of FRP boats is usually below 500t, such as military mine hunting boats, minesweepers, landing craft, transportation boats, etc.; civil high-speed passenger boats, fishing boats, yachts, lifeboats, work boats, and racing boats. The newly-built anti-mine warships of many national navies mostly use fiberglass hulls, decks and cabins. The "hunting" class mine hunter/minesweeper built by the UK, with a full displacement of 750t, a length of 60m, and a width of 10m, is the largest fiberglass ship to date. In the 1990s, China built a number of catamaran passenger ships with fiberglass hulls, and China-made fiberglass lifeboats have been exported to many countries.

FRP fishing boats began to appear in the late 1950s and early 1960s, which is another major change in the history of fishing boat development. At present, there are more than 2 million FRP ships in the world. Not only developed countries such as the United States, Japan, and Britain have developed rapidly, but also developing countries such as India and Thailand have also successively developed and built. Practice has proved that FRP is an ideal material for the construction of small and medium-sized fishing boats. Therefore, many countries have adopted measures to restrict the production of wooden ships and formulated preferential policies to support the development of FRP ships.

Almost all of the fishing boats fishing in the U.S. offshore are made of FRP, and wooden fishing boats have been eliminated. The annual amount of FRP used for shipbuilding is more than 200,000 tons.

Japan's FRP fishing boats have developed the fastest. By 1995, wooden fishing boats accounted for only 11.1%, basically replacing wood with fiberglass.

South Africa was the first country in the world to build a larger FRP fishing boat. In 1960, a 20.7 m fishing trawler with a sandwich structure using PVC as the core material was built, with a displacement of 95t. The speed is 11 knots.

In 1980, India had 20,000 FRP motorized fishing boats, and now there are still more than 2,500 renewed annually.

The development of FRP fishing boats in Peru, Poland and other countries is also fast, and large quantities of FRP trawlers and purse seine fishing vessels below 28nl have been produced and sold abroad.

Britain, France, Germany, etc. have also built many FRP boats. Due to the need for environmental protection, countries all over the world are logging limited amounts of wood, and the economic benefits of FRP fishing boats are better than wooden boats. Therefore, replacing wooden fishing boats with FRP fishing boats has become inevitable abroad.
