FRP material (also known as glass fiber reinforced plastic, the internationally recognized abbreviation is GFRP or FRP), is a wide variety of composite materials with various properties and wide applications. It is a new functional material made of synthetic resin and glass fiber through a composite process.
FRP material has the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation, slow heat transfer, good thermal insulation, good transient ultra-high temperature resistance, easy coloring, and electromagnetic wave transmission. Compared with commonly used metal materials, it also has the following characteristics:
Because FRP products can be designed and manufactured according to different use environments and special performance requirements, as long as you choose suitable raw materials, you can basically meet the performance requirements of different uses for the product. Therefore, FRP material is a designable material variety.
FRP material products, one-time production and molding, is another significant feature that is different from metal materials. As long as you select the appropriate material laying method and arrangement procedure according to the product design, the FRP materials and structure can be completed at one time, avoiding the secondary processing usually required for metal materials, which can greatly reduce the material consumption of the product and reduce The waste of manpower and material resources.
FRP material is also an energy-saving material. If the manual paste method is used, the temperature during molding is generally at room temperature or below 100°C, so its molding and production energy consumption is very low. Even for those using mechanical molding methods, such as molding, winding, injection, RTM, injection, pultrusion and other molding methods, the molding temperature is much lower than that of metal materials and other non-metal materials, so the molding energy consumption can be Significantly reduced.
In summary, compared with traditional metal materials and non-metal materials, FRP materials and their products have the characteristics of high strength, good performance, energy saving, greater product design freedom, and wide product adaptability. Therefore, in a certain sense, FRP material is one of the material varieties with a very wide application range and great development prospects.
At present, my country's FRP industry has a certain scale. It has made great progress in terms of product variety and output, as well as in terms of technical level, and has played an important role in the construction of the national economy.
