Types of Bonds in Marine Vessel Construction

Based on the passage, the choice of bonding method is critical in marine vessel construction because:

• it ensures the structural integrity and safety of the vessel.

• it reduces the cost of paint used on the vessel.

• it determines the color of the vessel.

• it affects the speed at which the vessel can be built.

Fill in the blank: Permanent bonds are achieved through the use of powerful chemical adhesives like Crestabond or Crestomer, polyurethanes, and methacrylates that create a strong, durable molecular bond between surfaces. This method is called _________.

• Thermal Welding

• Surface Coating

Fill in the blank: Fiberglass and other fiber-reinforced composites are laminated onto structures to dramatically increase their strength and durability for marine applications. This process is known as _________

• Fiber Reinforcement

• Electroplating

• Anodizing

• Galvanization
