Early carbon fiber composite materials were used in small patrol boats and landing ships. The relatively poor manufacturing quality and hull rigidity limit the length of the ship to 15m and the displacement to 20t. In recent years, with the reduction of composite material design and preparation costs, and the improvement of mechanical properties, composite materials have begun to be applied to large ships, such as mine-hunting boats and light frigates. With the development of technology, the length of ships has been increasing steadily. Now there are 80-90m all-composite naval ships.
The United States is the country with the most advanced development of composite materials science and technology, the most widely used composite materials, and the largest dosage. In terms of the application of marine composite materials, its scale and technology are at the forefront of the world. The U.S. Navy built a transportation boat using polyester fiberglass in 1946. It was the world's first composite ship, and subsequently manufactured fiberglass landing craft and work boats.
After entering the 21st century, the United States has further strengthened the application of composite materials in ship construction. It uses a new high-strength carbon fiber / vinyl resin sandwich structure to replace low-strength fibers such as traditional glass fiber. The new ship built has high stability and fast speed. And has stealth, anti-submarine, anti-mine capabilities. The European composite shipping industry is also very developed.
In the mid-1960s, the United Kingdom used FRP to manufacture a large 450t minesweeping boat and a 625t mine hunting boat. In 1973, it used composite materials to build an all-fiber reinforced plastic anti-water mineboat. In the 1990s, the United Kingdom successfully used carbon-glass hybrid fibers to build motor boats and patrol boats. With the development of technology, in recent years, it has successfully used recycled plastic bottles to reprocess materials to build ships, which not only reduces costs, but also meets the requirements of biological materials. The development direction of degradation and recycling. In the 1990s, Sweden successfully developed the world's first composite stealth test boat, and gradually developed a construction method characterized by high-performance carbon fiber and sandwich structure, developed and built a combination of advanced composite material technology and stealth technology. The integrated series of light destroyers have been successfully launched into service.

Japan has been building FRP boats since the 1950s, and has achieved good results in the construction of high-performance boats, rowing boats and luxury yachts. In the 21st century, Japan began to research and manufacture high-performance composite military ships. At present, the first FRP minesweeping boat has been successfully built and put into use.
The research and application of composite materials in China began in 1958, and the first FRP work boat was born in Shanghai. In the mid-1970s, a minesweeper test boat with a total length of approximately 39m was developed. After that, the research and development of GRP / CM anti-mine minecraft was interrupted for more than a decade. Since the 1990s, with the development of technology and the introduction of technology, China has produced a large number of yachts, sailing boats, rescue boats, and high-speed patrol boats, law enforcement boats, and anti-smuggling boats such as public security, armed police, maritime surveillance, and customs. Waiting for paramilitary boats, but so far has not designed and built a high-tech naval anti-mine mine ship.
Compared with foreign countries, the application scope and scale of China's marine composite materials are still relatively small, but with the rapid development of carbon fiber composite materials in China, the development of domestic marine carbon fiber composite materials is eye-catching. The carbon fiber composite material sonar deflector and carbon fiber composite material radome have all formed relatively mature applications.
It can be seen from this that domestic has great potential in the use of carbon fiber composite materials for marine use. Although there is still a certain gap between the whole and foreign countries, it is believed that with the efforts of many materials people, the future development gap of domestic marine composite materials will be gradually shortened. Even beyond.
