There will be sales in the building materials market. FRP is a material made of glass fiber composite with one or several thermosetting or thermoplastic resins, such as phenolic resins, epoxy resins, polyester resins, polyimide resins, etc. FRP is a new type of composite material developed in the early 20th century, which has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, sound insulation and so on.
The earliest composite material to appear was fiberglass, which has nothing to do with steel. There is no iron in FRP at all, and it is not a composite of glass and steel.
The first FRP is a material made of glass fiber and phenolic resin. It is a liquid raw material that impregnates glass fiber with phenolic resin, is preformed by molding, and then cured by phenolic resin to make FRP. Corrosion-resistant and long-lasting.
FRP is a high-quality composite material. It has special anti-corrosion function for various corrosive media such as acid, alkali, salt, oil, etc., and will not corrode. The life span of ordinary PVC is 15 years, while the life span of FRP is 50 years.
FRP has the advantages of high strength, and the reasons are:
Ordinary glass is a brittle material with low strength, and if the molten glass is drawn into very fine glass fibers, its properties will change greatly. Fiberglass is soft and can even be woven into cloth. At the same time, the finer the fiberglass, the stronger it is.
The strength of FRP can be compared to reinforced concrete. In reinforced concrete, it is mainly the steel bar that bears the external force, but the concrete is indispensable, it bonds the steel bar into a whole, not only gives the building component a certain shape, but also increases the strength. In FRP, glass fiber acts like steel bar, while phenolic resin plays the role of concrete, and the combination of the two gives FRP amazing strength.
FRP not only has high strength, but also has excellent corrosion resistance, thus becoming an important corrosion-resistant material. Lead used to be a corrosion-resistant metal material, and it was resistant to the corrosion of sulfuric acid, which is highly corrosive. The reason is that lead and concentrated sulfuric acid react to produce insoluble lead sulfate, which becomes a dense protective film covering the surface of metallic lead, so the reactor and pipeline of chemical plants are often lined with lead, and enamel lining can also be used.
If FRP is used instead, the corrosion resistance meets the requirements. FRP is also used for valves, pumps, fans, suitable for transporting corrosive liquid car car and train tanker, in the chemical plant to make storage tank for corrosive liquid, waste acid and waste liquid pool village and large area of anti-corrosion ground. Petroleum is also very corrosive, FRP can be used instead of steel pipes to make oil pipelines, oil trucks, greatly saving steel.

FRP is a fiber-reinforced plastic material.
FRP, also known as GFRP, is a fiber-reinforced plastic, which generally refers to glass fiber reinforced unsaturated polyester and epoxy resin.
With phenolic resin matrix, the reinforced plastic with glass fiber or its products as the reinforcing material is called glass fiber reinforced plastic, or glass fiber reinforced plastic, which is different from tempered glass.
Due to the different types of resins used, there are polyester FRP, epoxy FRP, phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less utilization, corrosion resistance. It can be used instead of steel to make machine parts and shells of automobiles and ships.
With the development of China's FRP industry, as a plastic-based reinforcing material, it has been expanded from glass fiber to carbon fiber.
Boron fiber, aramid fiber.
Alumina fiber and silicon carbide fiber, etc., undoubtedly, the reinforced plastics made of these new fibers are some high-performance fiber-reinforced composite materials, and the common name of FRP cannot be summarized.

If according to the material attribution of FRP, it should belong to the series of composite materials, because in the production process of FRP, glass fiber is mainly used.
In addition, some reinforcing materials are formed after merging, so Qi Ruhu is called FRP, which can also be called fiber reinforced plastic. The supplies included in the reinforcing materials are: felt, yarn, tape, glass cloth and other materials.
Second, what are the uses of FRP?
When it comes to the use of FRP, it is too many to count, because it can basically be applied to any field, including the construction field, chemical field, transportation field, aviation field, road field, electrical industry, communication engineering and so on.
1. In our daily life, there are many FRP materials that can be accessed, such as safety helmets can be seen on some accessories of motorcycles.
It is also possible to use FRP material, including some Huagao barrage pots are also made of FRP material, and even the shells of many household appliances are also made of FRP.
2. After the secondary processing of FRP, it can also be used in different environments and fields, such as the production of FRP as food cans, FRP pipes or FRP handicrafts and so on. Even in our bathroom, when doing construction, the roof plate used on the roof can also be based on FRP.

Summary. Kiss.
1. Glass fiber, which is a kind of composite material, is usually used in aerospace, railway, construction, furniture, bathroom and other fields, and its strength is similar to that of high-grade alloys.
2. Epoxy resin, with its excellent viscosity and chemical resistance, is also a kind of polymer, and the process is flexible and can usually be made into coatings, adhesives, pouring substrates and so on.
3. Phenolic resin matrix, its heat resistance and burning resistance are excellent, and small molecules will be emitted when curing, which is generally used as a composite material.
What is the raw material of FRP?

FRP combines the advantages of glass and steel, its weight is not large, the density is normal, and it is one to one-fifth of the four things of carbon steel, and its tensile strength is about the same as carbon steel, and sometimes it is even better than carbon steel.

The main test items are magnetic properties, density, elastic modulus, thermal expansion coefficient, resistance value, etc.
I am from the University of Political Science and Law, and the real questions for the postgraduate entrance examination are not available everywhere, in Changping District, only the Blue Dream Bookstore on the campus of the University of Political Science and Law has them, if you are in the city, I recommend that you go to the bookstore on the campus of Xueyuan Road to buy them, and there are standard answers. Finally, it's important to advise you that past questions are important! But it's not cheap.
Hello, see that your question is about to be squeezed out of the list of questions by new questions, and if the question is not expired, points will be deducted and bounty points will be forfeited! So I'll give you a few suggestions: >>>More
