In recent years, the shipbuilding industry has gradually turned its attention to unsaturated polyester resins, a new material. Unsaturated resin has become a high-profile new favorite in the field of shipbuilding due to its lightweight and high-strength properties. Unsaturated resin is a thermosetting resin with excellent molding properties and chemical stability, and is suitable for manufacturing complex-shaped hull structures. Compared with traditional metal materials, the hull made of unsaturated resin is lighter and can provide higher strength and corrosion resistance, greatly extending the service life of the hull.
The application of marine unsaturated polyester resins is also constantly innovating, and manufacturers are actively exploring its combination with fiberglass reinforced materials (FRP) to further improve the strength and rigidity of the hull. The structural design of this composite material can effectively reduce the weight of the hull, improve the fuel efficiency and navigation performance of the ship, reduce operating costs, and meet the urgent needs of today’s shipping industry for energy conservation and emission reduction.
Not only that, the unsaturated resin material itself has good molding performance, which can meet the requirements of ship designers for complex shapes and streamlined shells, providing shipyards with more design freedom. Ship manufacturers can more flexibly build high-performance ships that meet customer needs, thereby improving market competitiveness.
With the widespread application of unsaturated polyester resins in ship manufacturing, hull manufacturing processes and technologies are also constantly improving. In the future, we have reason to believe that unsaturated polyester resins will play an increasingly important role in the marine field and contribute more new possibilities to the sustainable development of the global shipping industry. The wide application of unsaturated polyester resins will bring more innovation and opportunities to the shipping industry, and push ship technology towards a more environmentally friendly, efficient and sustainable future.
