Fiberglass is a new type of shipbuilding material and an important part of the modern materials revolution. Fiberglass has not been used in shipbuilding for a long time, but it has already shown its strong vitality and broad development prospects. Fiberglass vessels include not only small vessels such as fishing boats, yachts, high-speed passenger boats, service boats, transport boats, speedboats, lifeboats, pleasure boats, sailboats, sports boats, minesweepers, etc., but may also develop fiberglass vessels with a length greater than 50 meters.

The characteristics of fiberglass vessels are light weight and high strength, with great potential for weight reduction, suitable for high-performance ships and racing boats with weight restrictions; corrosion resistance, resistance to marine organism attachment, more suitable than traditional shipbuilding materials; non-magnetic, making it the best structural and functional material for minesweepers and mine hunters; good dielectricity and microwave permeability, suitable for warships; ability to absorb high energy, good impact toughness, ships are not easily damaged by collision or compression; low thermal conductivity, good heat insulation, suitable for building fire-resistant lifeboats, fishing boats and refrigerated ships, etc.; the hull surface can reach a mirror-like smoothness and can have various colors, especially suitable for building various aesthetically pleasing yachts; good designability, able to achieve optimized design through material selection, lamination research and structural modeling according to the different requirements of ship structural components; good integrity, the hull has no seams or gaps, preventing leakage; simple molding, more labor-saving than steel and wood, and mass production is particularly good, with great potential to reduce costs; convenient maintenance, maintenance costs are much less than other materials of vessels, good economic performance throughout the life cycle.
