Composite panel for ship and manufacturing method therefor

Abstract

Disclosed are a composite panel for a ship, a plurality of which form the shape of a resistance reduction apparatus when coupled to a frame installed at the deck of a ship, and a manufacturing method therefor. The composite panel for a ship may comprise: a body part comprising a plate-shaped core, and a board formed of a fiber-reinforced composite and joined to the outer surface of the core; a fastening part which is formed on the outer side of the core along the circumference of the body part and is formed by stacking the board in plural piles; a ramp part which is formed between the body part and the fastening part, and comprises a slope which connects the outer surface of the body part and the outer surface of the fastening part; and at least one pin which is inserted into the body part in the thickness direction.

Description

technical field [0001] The invention relates to a composite material plate for ships and a manufacturing method thereof. Background technique [0002] Generally speaking, in the process of sailing, the ship will be subjected to the resistance of water and waves, and at the same time, it will also be subjected to the resistance of air and wind. In fact, air resistance becomes a factor that deteriorates the fuel efficiency of the ship, slows down the top speed of the ship, and reduces the maneuverability of the ship. [0003] Especially for ships such as ultra-large container ships and cargo ships, the shape of the main hull and cargo on the water surface is close to a cuboid and a higher position is exposed from the water surface, so the area subject to wind pressure is large. In this case, air, wind, When the ship collides with the water surface, the resistance of deck swell (green water) to the bow is very large, so the bow side receives more increased resistance. If drag...

AI Technical Summary

Problems solved by technology

However, unit panels made of composite materials have material properties that make it difficult to join each other by welding

Even if it is pasted with an adhesive, the surface treatment of the adhesive surface is difficult, and foreign matter will reduce the adhesion and reduce the connection reliability.

[0006] In addition, the disadvantage of fiber-reinforced composite panels is that their strength in the thickness direction is weak

In particular, panels with a sandwich structure cannot fully exhibit the strength required to constitute a drag reduction device in the thickness direction
