CARBON FIBRE REINFORCED PLASTIC (CFRP) FERRY BOATS
[CODE NO. 1986]
The use of fibre-reinforced plastic has become firmly established in boat building over many years. The advantage lies in the simple practicability of free form shapes compared with the use of conventional materials such as wood or steel. This results in a very varied scope for design. With targeted use of sandwich constructions, it´s possible to produce lightweight components with high specific mechanical values.
The application of carbon fibers and epoxy resin, in combination with lightweight Nomex honeycombs enables a maximum optimization of weight and stability for uses in water sports from regatta boats, to rowing boats or highly specialized sailing yachts for racing purposes. Nowadays this material combination is also increasingly used for building luxury yachts.
When constructing pleasure boats or large scale production yachts the optimal cost-benefit-ratio of fiber-glass reinforced plastics has resulted in it being used as a standard material.
In the sectors of commercial shipping, passenger transport and the navy; for example ferries, cruise ships or frigates, special fire prevention properties are needed to offer the highest possible safety for the passengers and crew. Fibre-glass reinforced plastics can only fulfill these standards through the use of special raw-materials.
As a general rule the materials for ship and boat building have to be approved by the Germanischer Lloyd, Lloyds Register or Det Norske Veritas.
Carbon fibre reinforced polymer is a type of fibre composite material in which carbon fibres constitutes the fibre phase. Carbon fiber is a group of fibrous materials comprising essentially elemental carbon. This is prepared by pyrolysis of organic fibres. PAN-based (PAN-poly acrylo nitrile) carbon fibres contains 93-95 percentage carbons, and it is produced at 1315°C (2400°F). Carbon fibres have been used as reinforcement for albative plastics and for reinforcements for lightweight, high strength and high stiffness structures. Carbon fibres are also produced by growing single crystals carbon electric arc under high-pressure inert gas or by growth from a vapour state by thermal decomposition of a hydrocarbon gas.
CFRP materials possess good rigidity, high strength, low density, corrosion resistance, vibration resistance, high ultimate strain, high fatigue resistance, and low thermal conductivity. They are bad conductors of electricity and are non-magnetic.
Strengthening measures are required in structures when they are required to accommodate increased loads. Also when there are changes in the use of structures, individual supports and walls may need to be removed. This leads to a redistribution of forces and the need for local reinforcement. In addition, structural strengthening may become necessary owing to wear and deterioration arising from normal usage or environmental factors.
