Marine transportation products and other marine structural components constantly face environmental challenges. Therefore, a material like a fiberglass(GRP) that exhibits high resistance and requires minimum maintenance for extended periods is generally used. GRP is a lightweight and corrosion-resistant material that meets the design requirements and is highly reliable.
Composite materials like Glass-reinforced polymers (GRP) have been extensively used in the marine industry to overcome corrosion
issues experienced with steel, aluminum, and wood. GRP has been developed over the years to meet the growing and variable demand in the marine sector. GRP materials play a crucial role in consolidated manufacturing elements, including gratings, ducts, shafts, piping, and hull shells. In the present day, composites are employed in all areas of the marine sector for various components and structures, like hulls, propellers, bearings, exhausts, topside structures, radomes, sonar domes, railings, vessels of all types, valves, and other subsea systems.
Benefits of using fiberglass in the Marine industry
- Provide lightweight material with a high strength-to-weight ratio
- Provide dimensional stability to the structures for lasting performance.
- It offers corrosion resistance to help marine structures to remain free of deterioration.
- Lighter weight helps to reduce operating costs and improve efficiency,
- It allows combining multiple parts into one, reducing maintenance costs.
- Reduce noise, creating a calm operating environment.
- The design flexibility of fiberglass supports making complex structures.
- Increased stiffness provides stability.
Applications of fiberglass in the Marine industry
- Powerboats made of composites are becoming popular for their durability, high performance, and safety.
- Fiberglass is used in the shipbuilding industry for making stiffer hulls and decks.
- GRP materials are used to make navy ships because they can withstand extreme working conditions in the Ocean as well as impacts and fires
- GRP materials are used worldwide to produce vessels of fishing boats, small boats, hovercraft, and catamarans
- Fiberglass is used in masts and propellers.
- Repairing underwater structures, such as concrete or metal pillars, represents one of the most common and interesting applications of fiberglass in the marine environment.
- Fiberglass is used to repair various wood and steel structures in boats and ships.
