Discussion on the application of FRP in agricultural machinery
2024-04-30
Glass fiber reinforced plastic is a new type of composite material, the scientific name of glass fiber reinforced plastic. Since FRP has many advantages such as low density, high strength, acid and alkali resistance, non-magnetic and easy forming, it has been widely used in aviation, shipbuilding, construction, chemical industry, automobile and other industrial fields since its birth more than half a century. Among them, some famous automobile companies in Germany, France and other countries have manufactured millions of FRP shell cars, and the front and rear bumpers and instrument tables of cars have widely used FRP materials. The United States John Deere Company 9650CTS, 9750STS and many other models of tractors, combine harvesters are also widely used glass fiber reinforced plastic streamline covering parts, and extended to the domestic Deere Jia Lian, Deere Tiantuo products.
The main materials of FRP are glass fiber and resin. There are many outstanding advantages to the use of FRP materials in agricultural machinery. First, the physical modeling can be directly carried out, the shape and size of the product are not limited, and it can be convenient to produce complex, smooth and beautiful products; Second, the development cycle is short, the equipment is simple, and the investment is less; Third, after the mold is made, manual molding, simple operation, convenient deformation; Fourth, the cost is low.
The new product development speed of combine harvester, tractor and other agricultural machinery is getting faster and faster, and the design of appearance and the manufacture of covering parts have become an important factor affecting the development progress. The use of traditional sheet metal manufacturing methods, to form mass production, long cycle, large investment. The application of glass can be a good solution to this problem, especially in the trial production, small batch production stage, the advantage is greater. In addition, in terms of product improvement and innovation, FRP parts can meet the needs of users to seek new, different and beautiful. When developing the arc cab of 3518STS combine harvester, Deerjialian adopts a large number of FRP parts as covering parts, which greatly speeds up the product development speed and reduces the product development cost. Beautiful glass fiber reinforced plastic parts, smooth surface, beautiful, no traditional sensitive gold parts easy to rust, afraid of bumping shortcomings, beautiful cab, greatly improve the product image of the whole machine, improve the market share, to meet the needs of users. The engine cover, wheel arch cover and cab cover developed by Deere Tiantuo also use a large number of FRP parts, and the newly developed tractor has a beautiful streamline appearance, which has been recognized by the market.
With the development of the economy and the improvement of people's living standards, people have higher requirements for the machine not only in terms of function and reliability, but also in the appearance and color matching of the machine. Due to the advantages of FRP parts, it will have a wider application prospect in combine harvesters, tractors and other agricultural machinery.
