What materials are often used for deck stiffeners?

• A. Aluminum and Steel
• B. Bamboo and Composite
• C. Wood and Foam
• D. Concrete and Plastic

Answer: (C)

Using wood and foam as materials for deck stiffeners is a popular choice in composite construction due to their specific properties and benefits in marine applications. Wood offers excellent strength-to-weight ratios and is widely available, making it cost-effective and easy to work with. It has good mechanical properties that can be beneficial in providing the necessary support and load distribution for the deck structure. Additionally, wood is relatively lightweight compared to many metals, which helps keep the overall weight of the vessel lower, improving performance and fuel efficiency. Foam, on the other hand, is used in deck stiffeners for its lightweight nature and its ability to provide buoyancy. Closed-cell foams, in particular, are resistant to water absorption and provide thermal insulation. When used in conjunction with wood, foam can enhance the stiffness of the deck without adding significant weight, which is a key consideration in marine design. These two materials complement each other well, creating a stiff yet lightweight composite structure that can withstand the demands placed on marine decks. Their combination leads to effective stiffness reinforcement while maintaining overall performance characteristics of the vessel, making wood and foam an ideal choice for deck stiffeners.
