The advantages of aluminum fishing boats are as follows:
First, not afraid of subtle bumps, pits will occur after bumping but no water leakage, because aluminum alloy is resistant.
Second, lightweight, one-fourth lighter than the same style of fiberglass boat, fuel consumption is also saved by one-fifth, the weight of light can carry more people and goods.
Thirdly, the inner deck of the aluminum alloy fishing boat has a large area, and the glass fiber reinforced plastic is made of a mold. The wall of the mold is thick and the floor space is large, so that the fiberglass boat of the same length and width does not have a large space for the inner space of the aluminum alloy fishing boat.
Fourth, the aluminum alloy fishing yacht is easy to maintain, light and convenient, and can be towed.
Fifth, many aluminum alloy fishing boats or other boats are generally much cheaper than FRP.
The defects of aluminum alloy fishing boats have the following two points:
First, it is simple to hurt the paint, because the fiberglass boat is white, the interior is white after the scratch, so it is white, but the aluminum fishing boat is silver inside, or silver with primer. black. Therefore, it is particularly obvious after scratching, which is not beautiful.
Second, when the aluminum alloy fishing boat is empty, the hull is not as stable as the FRP boat, and it is slightly shaken.
Third, fear of impact, once a slight impact occurs, the aluminum alloy boat will be deformed and even leak.
Fourth, the life is short.
Fifth, do you think, in the hot summer, what do you feel when you sit on an aluminum fishing boat?
Sixth, the shape is single.
The advantages of FRP fishing boat are mainly as follows:
1. FRP is more resistant to corrosion than aluminum alloy
2. The FRP products produced by a certain production process are not easily deformed to some extent than the aluminum alloy.
3. FRP service life is longer than aluminum alloy.
4. More environmentally friendly, more economical, it is possible to burn more.
5. Not afraid of a slight impact, hardness and strength better than aluminum alloy, strong, some bulletproof clothes are made of fiberglass.
6. The shape of the FRP fishing boat is more cool, diverse, and can be molded.
The disadvantages of FRP fishing boats are mainly the following
1. It is slightly heavier than aluminum alloy, but the effect is not great.
2. Long-term temperature resistance is poor, the general ordinary FRP can not be used for a long time at high temperature, the general polyester at 60 ° C above the strength will be significantly reduced, generally only below 100 ° C;
General-purpose epoxy FRP has a significant decrease in strength above 70 °C.
However, high temperature resistant resin can be selected. We can order the materials according to the customer's requirements, so that the long-term working temperature is 200~300 °C. However, there is no need to use this kind of stuffy resin.
3. aAging phenomenon, this is a small problem, the general FRP boat can be used for at least 20 years, and the aluminum alloy can be used in ten or twenty years is very good.
4. the need for higher professional people to control the processing technology of FRP, because the interlaminar shear strength of FRP fishing boats is mainly based on resin, which is the shipbuilder's creation.
R & D and production teams can improve the adhesion between layers by selecting processes and using coupling agents. The most important thing is to avoid cutting between layers when designing products.
Finally, the farmer and pastor give you a popular science. From the perspective of process molding of FRP and aluminum alloy, a set of molds is required for the FRP boat, and the mold can be reused. In general, a set of 20-30 The glass fiber reinforced plastic mold of rice needs two or three hundred thousand (simple type mold), and does not contain labor costs. Of course, the two hundred and thirty thousand molds can also produce the quality of millions of boats.
Next, it is the cost of the material, and the performance and usage of the material need to be considered. Therefore, considering the construction of a ship alone, regardless of the impact of the weight of the ship on the speed of the ship, the farmer will summarize the sentence, the cost of the whole iron. The lowest, the second of aluminum alloy, the highest cost of FRP.
