Reasons For The Wide Application Of Honeycomb Composites In Boats

The structural materials of the yacht, mainly wood, steel, aluminum alloy, glass steel, the same strength materials, the lighter weight, it means saving power and speed, which is conducive to reducing emissions! The unique structure of the plastic honeycomb composite sheet, through the surface layer of different bonding strength, achieves the requirements of greater strength and lighter weight!

In addition to mechanical properties, processability and economy are also important factors in the selection of hull materials. In recent years, due to environmental awareness, the environmental impact of materials and wastes needs to be evaluated. The plastic honeycomb materials produced by our company use imported raw materials and have excellent technology to minimize the consumption of resources and energy.

At the Sydney International Boat Show, more and more yachts use composite materials, which is a very obvious trend as a hull. The reason is that the composite hull structure has a long service life and is more convenient for maintenance. At the same time, it has unparalleled environmental advantages in terms of manufacturing, use, maintenance and recycling.

The advantages of composite materials as a shipbuilding material are:

1.Light weight

 In addition to tensile strength and modulus, specific strength and specific modulus, the same strength is required. The required material weight is light, and the specific strength is higher than that of the metal material, indicating that the plastic honeycomb composite has excellent mechanical properties.

2. Good anti-fatigue performance

The fatigue failure of the composite material starts from the relatively weak fiber and gradually spreads to the bonding surface, and the interface between the matrix and the reinforcing fiber can effectively accelerate the expansion of the fatigue crack, so the fatigue resistance is good. The tensile strength of general metal materials is 40% - 50%, while the level of reinforced plastic is 70% - 80%

3. Non-magnetic

The composite material is non-magnetic and will not be magnetized in a large magnetic field, so the composite ship is not easily detected by the other magnetic detector, avoiding the magnetic mine torpedo attack, which is particularly important in the military.

4. Corrosion resistance

As long as the formula is reasonable in design, it has good corrosion resistance in acid, alkaline and many harsh environments. The boat made of composite material does not need to be painted, and it will not corrode after sailing for several years in seawater, reducing paint and so on. Maintenance costs, long service life

5. Designability

Composite materials can choose different polymers and reinforcing materials and different formulations, different molding processes to achieve different performance, according to the structural requirements of different parts of the boat, the material layer and structure optimization design

In addition, the composite material also has a series of advantages such as excellent high temperature resistance and shock absorption, which makes the plastic honeycomb composite material have various properties and has been widely used in boats.
